How to Cure and Prevent Cloudy or Green Water

How to achieve clear water here

Why your tank gets dirty

There are a number of potential causes for cloudy or green water in a fish tank or aquarium. It is important to be able to determine the cause of the cloudiness or green color in the water so you can correct any problems in the tank. For this reason, even though there are chemicals you can purchase at your local pet store, this should not be your go-to for clearing the water your tank. Yes, they will clear the water, but the underlying cause of the cloudiness or green color will persist.

Some of the reasons water becomes cloudy or green are essentially harmless or will resolve themselves over time and others are representative of an issue that needs to be dealt with. Cloudy water and green water are entirely separate issues, with different causes. Let’s first take a look at curing and preventing cloudy water and then examine how to cure and prevent green water.

Cloudy Water

Cloudy water in your aquarium is not always an indication that something is wrong. In fact, in most cases, the cause of the cloudiness will be resolved on its own or with the help of the filter and you don’t need to do anything. However, anytime the water looks cloudy, it is important to assess the situation and the environment to determine the cause. Once you know the cause, you can eliminate it if need be and get rid of the cloudy water.

If your aquarium is new and you haven’t even had any fish in it, yet the water has turned cloudy, the problem is probably due to accessories in the tank. If these accessories are new and haven’t been properly rinsed off prior to introducing them to the tank, they can cause the water to turn cloudy. If it is an accessory that is safe for use in aquariums, then the filter and/or regular water changes will remove the cloudiness. If the accessory is not intended for use in an aquarium, it may be dissolving or disintegrating in the water, which is dangerous for your fish. The object should be removed and the water completely changed.

If you have had fish in your aquarium for a few days to a couple of weeks (depending on the number of fish in the tank) and the water has turned cloudy, it is likely due to the fact that the filter hasn’t completely cycled the water yet. The filter is responsible for cleaning the water of the waste left by the fish. If the setup is new, the filter takes time to go through one full cycle. Once it does, the cloudiness will be cleared up.

Sometimes when an aquarium has only been set up for a few minutes or even hours or it has just had a large volume of water changed, it can have a gray cloudy look to it. This is due to tiny bubbles of oxygen that are suspended in the water. You may have seen something like this in a freshly poured glass of water. This is nothing to worry about; the bubbles will dissolve in the water or make their way to the surface.

If you have wooden accessories in your aquarium, they can sometimes release tannins into the water. If your aquarium water looks like weak tea and you have any wooden accessories, then this is the cause. This cloudiness and the tannins that cause it are usually for your fish. However, if this happens, be sure to monitor the PH of the water regularly because the tannins might soften the water and cause the PH to drop. If this happens, you will need to adjust the PH level of the water.

If you have had an aquarium for a long time, then most likely you won’t deal with cloudy water, unless you introduce new accessories into your tank or have just change a large amount of water. More likely, with older aquariums, you will have a problem with your water turning green. Green water in your aquarium means you have an algal bloom. Yup, you read that right. Just like the algal blooms you may have read about in the news that fill up many of our lakes and oceans, your aquarium water can be filled with an algal bloom.

In general, the presence of algae in your aquarium is a good thing. It’s a sign of a healthy tank that can support life. However, you don’t want this growth of algae to get out of control and form an algal bloom. Algae on the glass is beneficial but algae in the water is unsightly. There are a few reasons why there could be too much algae growth in the water, including the following:

Overfeeding: Whenever you feed your fish, there should be no food left floating in the water within a few minutes after feeding. If there is leftover food, then you are giving your fish too much and it could cause algal blooms to form. You can easily fix this problem by reducing the amount of food you give your fish.

Infrequent Water Changes: Algal blooms can grow quickly if there is too much time between water changes. Be sure to do small water changes regularly to prevent the buildup of nitrates, something algae thrive on. If your tank hasn’t had any water changes in a while, then you need to do a few large water changes a few days apart, replacing as much as 25%-30% of the water each time, until the tank is clear.

Too Much Light: If water changes and feeding are under control, then too much light might be the culprit. Algae thrive on light, so cutting back on the amount of light your aquarium is getting might just solve the problem. Also, if direct sunlight is hitting the aquarium this can trigger an algae bloom.

Poor plant growth: Plants and algae feed off the same nutrients in the water. So if you have good plant growth, this remove the nutrients from the water that algae rely on.

Healthy Water Means Healthy Fish

Just remember to assess the situation any time the water in your aquarium doesn’t look right. While it might not amount to anything important, you probably don’t want to risk the health and safety of your beloved pets by ignoring the situation. Keep a close eye and keep the water clean to have happy fish you will enjoy for a long time to come.

Aquascaping is the art of setting-up, decorating and arranging aquatic plants along with stones, rocks, driftwood or cavework in an aesthetically pleasing manner. Also termed as underwater gardening, aquascaping was first introduced to the world way back in 1990’s by Takashi Amano from Japan, who made the natural underwater gardens look like dreamscapes. Although it is possible to create an aquascape with plants only, it can also be set up with fish as well as plants; or with rockwork, hardscape and no plants by following some specific methods.

If you find it difficult to create an aquascape then scan through the many examples of good aquascape scenes on the internet and pick a scene that you really like and that you can replicate.

Basic Principles for Aquascaping

To reach the perfection in the design of your aquascape you must follow a few important principles that are listed below:

Simplicity is the key – While aquascaping is all about imagination, it is recommended that you follow a particular style and maintain simplicity which would make the aquascape look more appealing to the human eye.
 
Choosing the aquascaping style – There are several major styles that you can choose from, which you can create a visually-enticing aquascape. These include the Japanese-inspired nature style, the garden-like Dutch style, the jungle style and many others. While the nature aquarium style is the re-creation of terrestrial landscapes – mountains, hills, valleys, etc., the Dutch style is characterized by terraces or raised layers containing distinct types of plants with different leaf types.

Maintaining Proportion- To maintain harmony in the aquarium, it is crucial to strike the perfect balance between plants, decorative items and fish as well as between filled and empty spaces in the aquarium. Also, arrange plants, rocks and wood in a manner that there is a balancing contrast of light and dark spaces.

Use your imagination- There are no defined rules for aquascaping. Use your imagination to make a beautiful aquascape that has clean water and an appropriate amount of light, CO2, and other essential elements.

To ensure proper care, maintenance and success of an aquascape, aquascapers must keep in mind several factors to strike balance in the closed system of the water tank. These factors include:

  • aquascape with clever use of various plants and driftwood

    Filtration System

  • Liquid fertilizers
  • Medium to high level of lighting
  • Maintaining the correct amount of carbon dioxide to support photosynthesis
  • Frequent water changes
  • Substrate and fertilization
  • Algae control

Plants and Plant Types

Besides the layout, style and design of an aquascape, aquascaping require specific ways to ensure proper care and maintenance of plants underwater. One of the most crucial things that aquascapers must keep in mind is choosing healthy and vibrant plants. Also, they must be trimmed to get the desired shape and positioned properly using a thread. Before beginning, you must know the plants and plant types that we shall discuss now!

Carpet Plants: Just as the name suggests, carpet plants are used by aquascapers to create a mat of plants or a lush of green lawn, making the underwater garden more beautiful and attractive. You can choose foreground pl ants such as Hairgrass, Dwarf Baby Tears, Java Moss, Water Wisteria or Willow Moss as they stay low to the ground and spread horizontally across the floor of the water tank.

Fast Growing Plants: When you begin with aquascaping, you can choose fast growing plants like hornwort, Vallisneria, Cabomba and Hygrophilia that would grow quickly, with no effort and would not even put a hole in your pocket. Other stem plants including sword plants, Java fern are also suitable but a little expensive.
Floating plants: While a number of floating plants can block light, many aquascapers prefer using them for visually-enticing aquascape. These plants include Hornwoot, Java Moss and Najas.

Artificial Plants: While using artificial plants is not considered aquascaping, it is one of the easiest ways for beginners. So, if you find it difficult to care for and maintain natural plants, you can go for artificial plants that do not require light or water parameters.

Location for Short, Large and Bushy Plants

To create a beautiful landscape underwater, it is essential for aquascapers to place the plants in an aesthetic manner. The major aspect to keep in mind is the focal point. It can be anything like a rock, a piece of driftwood or a bunch of plants or even one dominant plant. It is recommended to begin with carpet plants at the foreground and place the bushy and large plants at the background.

You can begin with the focal of the water tank and continue with the low-growing and mid-growing plants. At the end, place the higher plants. You can choose an appropriate composition such as the concave set up, the convex set up, the rectangular set-up, the triangular set up, or the Iwagumi set-up.

Different Coloured plants

To create in-depth perspective and make the aquarium look more natural, aquascapers use plants of different colours and sizes. Plants can be grown in groups and with rich colour contrast. Commonly used plants for colour contrast and highlights include lutea, lucens, wendtii, walkeri, and becketii of the Cryptocoryne species, Ammania, Alternanthera reineckii and Rotala.
Notably, 3 plant species per foot would be preferred to ensure good colour contrast.

Open Spaces for Fish

Before you kick-start aquascaping, you must understand that plants as well as fish are EQUALLY important in your water tank. When you provide the best conditions for your plants to stay healthy, you are providing a healthy environment for the fish as well. At the same time, it is a must to wisely use spaces between plants by creating imaginary streets as well as pathways. Also, make sure that you have as must open space as must filled space to provide space for your fish to lively comfortably and happily.

Hardscape: Use of Bogwood/Driftwood

Hardscape is one of the most commonly used techniques used by aquascapers across the globe. It involves using driftwood, rocks and resin sculptures. Driftwood adds a decorative touch to the aquarium, while making it look natural. The wood can be the main focal point, around which the plants can be placed. Many aquascapers prefer using the Malaysian driftwood or manzanita branches, depending on their preference.

Use of Rocks and Stones

In addition to wood, aquascapers use rocks and stones at the heart of their aquarium to create a natural-looking aquascape underwater. You can place boulders, large cobbles and smaller pebbles aesthetically in the water tank to further enhance its beauty. The classic way to use rocks is to place 2-4 flat rocks on the bottom of the aquarium and then arrange other rocks in the order of their size. Alongside, you can also add airstones and submersible lights to create visual effects and make the water tank more attractive.

Get Started!

Aquascaping is not all about creating a plan and sticking rigidly to it. Sometimes it is better to do a quick sketch up and then proceed to plant according to your rough draft. Then when it’s all laid out, you can see that it might not be right so you will need to rearrange things until you get it right. And don’t forget plants do grow and some grow more than others. So your aquascape will actually develop over time.

Aquascaping is all about imagination and creating enchanting visuals that appeal to the human eye. So, make sure that you use your imagination to create an amazingly-looking aquascape. Happy aquascaping!

Tropical fish keeping on a budget

While aquarists far and wide agree that fishkeeping is a fascinating hobby and trade, it can easily become an expensive one as well. The staggering number of new products always being released is enough to make anyone believe that an aquarium is a major investment. However, if you keep things simple and aren’t afraid of a little bit of DIY work, you can enjoy an amazing fish tank without breaking the bank in the process.

There are two major elements to keeping a tropical tank on a budget: reducing your start-up costs and keeping your tank maintenance low-cost. Making the correct choices in both aspects will ensure that you end up saving significant sums of money in the long run.

Reducing start-up costs

The first opportunities to save money come when you begin collecting supplies to set up your fish tank. Depending on what products you buy and the sources from which you buy them, you can end up earning yourself substantial savings, or spending an unnecessary fortune.

Naturally, getting a smaller tank will decrease all of the associated costs that you will have to deal with afterwards. However, small tanks can be difficult to properly take care of, so you are encouraged to choose a small tank only if you feel like you have enough experience to make it a success, especially if you are on a budget.

Some of the best deals for aquarium equipment can be found through second-hand sources such as classifieds sections and fishkeeping forums. Buying second-hand equipment can vastly reduce your start-up costs, but must be done carefully. Everything has a shelf life, and you can expect to replace used equipment more frequently than you would if it was new.

Creatively sourcing your aquarium supplies can help you save in many ways. For example, you could forego using expensive substrates like black Tahitian moon sand and instead opt for pool filter sand that, while not specifically made for aquarium use, is cheap, clean, and natural enough to use on a budget without risking the health of your fish or affecting your filtration.

Sometimes people will give away a leaky aquarium that is otherwise sound. Such an aquarium can be repaired for just the price of a tube of silicone and a bottle of nail varnish remover. Use a blade to remove the old silicone from the inside of the aquarium. Thoroughly clean the joints. Then spread a thin bead of silicone and reseal the tank. Use a finger along the seam to smooth the silicone and voila a new tank. You can also re-seal any tank that springs a leak.

Another great way to save money on your start-up costs is by making your aquarium setup a DIY project. Many common aquarium appliances can be made using various household and workshop items:

  • Sponge Filters – If you buy a simple power head and a brick of filter sponge, you can use a plastic tube to connect the inlet of a power head with the other end of the tube inserted into the sponge. Point the outlet towards the surface of the water and you have a surprisingly good filter at a fraction of the cost.
  • Sumps and refugiums – Ambitious DIY aquarists can build their own sump with relative ease. If you have spare tank handy and don’t mind doing a small bit of plumbing work, you can enjoy the benefits of a sump without having to pay for one! This is a great option for tanks that are damaged or scratched.
  • Aquarium stands – You can use a solid piece of furniture to place your aquarium on. A table of exactly the right size can be purchased and used. These can be bought second hand and used. Make sure that they are sturdy and level and support the whole of the aquarium base. If needs be place a solid sheet of wood on the base to support the aquarium.

    Aquarium lids – This is an ideal DIY project. If you have some DIY ability this is an ideal first project that will not be costly if you make a mistake. Materials can be bought from your local DIY store. You can also improve your design over time.

Collecting your aquascape decorations locally is another way to save some cash on your setup. Why pay for exotic Amazon driftwood to be delivered to your door if you have a river or a forest nearby? With a little bit of time, some careful selection, and a thorough cleaning and soaking, you can get your entire tank’s decoration done for free. Rocks and stones can be collected in the same way.

Making choices that save money over time

There are lots of ways that you can enjoy tropical fishkeeping on a budget, and a great deal of them rely on reducing the long-term costs of keeping a tank. Putting any of these cost-saving measures into practice with your tropical fish tank will ensure that you keep your expenses low.

  • Make your tank plantless—Live plants are wonderful additions to tropical tanks, but they need lots of light and those lights need lots of energy to run. If you want to save money in the long run, you might want to leave the plants behind.

  • Use low-maintenance, low light plant varieties and keep them nourished with inexpensive LED lights whenever possible. Incandescent and halide lamps can get costly over time. Buy a few easy varieties that grow fast.
  • Do your own repairs. Most filters have repair kits that are used to replace parts that wear out. The kits are a fraction of the price of a new filter.
  • Condition your water slowly—If you want to avoid conditioning your local tap water with expensive chemical products, let the chlorine naturally evaporate before using it in your tank. You can even try collecting rainwater if your tap water is too hard.
  • Grow your own live food—Fish food is a constant cost that continually adds up over time. If you choose instead to invest some energy in cultivating brine shrimp or daphnia or digging worms from the garden, you can enjoy an effectively unlimited supply of high quality live fish food.

Live food rearing here

  • Make your own dried fish food – There are many fish food recipes based on prawns, spirulina or spinach, flour, eggs, fish and other ingredients mixed in with multivitamins. The recipe is blended together then baked on a low heat to dry. The result can be broken into small pieces and frozen.
  • Insulate your aquarium – Heat loss can result in additional energy costs and make your heater work harder, wearing it down faster in the process. Insulating your aquarium to minimize heat loss will save you money over time—even if it is only partial insulation.
  • Set up a low maintenance Walsted aquarium.
  • Set up a temperate aquarium without a heater.
  • Stock your aquarium by breeding your own fish. To obtain different species just advertise and swap your excess brood. It may take some time, but you will obtain the variety of fish that you want for just the price of the initial adults.
  • Buy young fish and grow them to the size you want. Adults are more expensive to buy and won’t adapt to your aquarium as well as young fish.

Common cost-saving mistakes

Some beginning aquarists, in an attempt to save cut corners and save money, make a number of grave mistakes that can end up costing them the entire aquarium if left unchecked. A few examples of these are listed below:

  • Buying cheap low quality equipment such as heaters, filters and lighting is a bad mistake. A heater that fails can chill your fish or even get stuck and cook them! A filter that fails will pollute your water.
  • Using sunlight to light your aquarium—A tropical aquarium needs both heat and light, so placing your aquarium in direct sunlight seems like the perfect cost-saving solution right? Not quite! Rather than killing two birds with one stone, this will probably kill your aquarium population by causing an uncontrollable algae bloom.
  • If you don’t buy a heater, tropical fish will slowly die of cold at night or in winter.
  • Insufficient Filtration – Yes, larger filters tend to cost more, but it is always better to err on the safe side and go for a larger filter than to find yourself suffering from insufficient filtration.
  • Not testing the water—Water testing kits are not the kind of product that you want to skip out on in order to save some cash, even if you are an experienced aquarist. Be sure you know your water’s ammonia, nitrate, and nitrite levels, as well as its hardness and pH before you start adding fish.
  • Do not try to repair a tank with a cracked glass. Finding and fitting a new pane of glass is as difficult and costly as buying a new or second aquarium.
  • Buying cheap fish that are unhealthy. By all means shop around and see if someone is giving away fish or selling at a low price. But always make sure that the fish you are buying are healthy and the other seller’s fish are also healthy. Sick fish don’t just die they also pass illnesses to your other fish.

If you avoid these three common pitfalls and follow the guidelines set out above, you should be able to enjoy significant savings on your tropical fish tank. If you get lucky enough to find good deals on your tank’s necessities, you can end up with a beautiful aquarium at a fraction of the price it looks like it cost!

The plantless aquarium

How to approach plantless aquarium design successfully

Plantless aquarium design can be very enticing both for beginning aquarists and for more experienced ones, but making your plantless aquarium a success depends on a number of key factors that need to be kept in mind during your aquarium set up and thereafter as well. Plantless aquariums are often considered barren-looking by hobbyists in the aquarium trade, but with the right aquascaping approach they can offer their owners a uniquely serene, zen-like sense of beauty.

There are two essential prerequisites to successful plantless aquarium design: handling the technical aspects of healthy water conditions and filtration without the plants’ help, and designing your aquarium with an eye for sublime beauty in such a way that you do not feel the need to hide your aquascape behind plants.This requires maximising the artful use of other aquarium materials. The first order of business is making sure that your technical needs are taken care of.

Step one: compensating for a plantless tank with filters and algae control

The first two issues that you should consider with plantless aquarium design are the important role that plants play in the nitrogen cycle and in algae control. Fortunately, both of these issues can be resolved reasonably well through careful planning. Plants can make some aspects of your aquarium easier to take care of, but in the long run you can enjoy a successful tank without them as well.

When it comes to filtration, you want to maximize the ability for beneficial bacteria to grow in your tank since you will not have the benefit of ammonia-absorbing plants to rely on. This could mean increasing the size of your filter, using a rocky gravel substrate, or both. Gravel will provide additional surface area for the necessary bacteria to grow, which can help out immensely.

Gravel must be more carefully chosen to add visual interest. There are various grain sizes of gravel to consider and many colours to choose from. The texturing effect and colour of the gravel compared to the rocks and the fish should provide a stunning contrast.

Sand is also a worthwhile substrate to consider, although maintenance and cleaning is generally easier with gravel. Most fish tend to prefer sand as a more natural substrate and some require it in order to begin breeding and spawning. In either case, your substrate should be rather thin, since you do not have to worry about giving anchor to any plant roots.

Also, without the delicate needs of plants to worry about, you can set up your filter for more water flow. This can help ensure that the tank water does get thoroughly filtered without the need for plants, and will help with algae control as well.

Dealing with algae in a plantless tank

Despite all the time you spend on making your plantless aquarium design look great, if you leave your tank near a sunny window for a week you can expect a full-blown algae bloom to occur. In order to protect your tank from algae, you will need to maintain a consistent algae cleaning and light reduction program. Using a UV sterilizer may help here.

Prevent algae here

Even without a UV sterilizer, frequent water changes and careful monitoring of your water’s nutrient levels will be important to avoid encouraging algae growth. You can also invest in algae controlling chemicals, but these should be considered a last resort, as they may affect the fish and may not be necessary in the long term, unless your algae situation really gets out of hand.

Paying attention to your lighting when planning your plantless aquarium design is important for this reason. Without plants, you have no need for specialized halide lights and indeed this kind of lighting will encourage algae blooms to occur regularly, putting your fish in danger and turning your beautifully serene tank into an unsightly green cesspool. If you notice algae getting out of hand, you can always “black-out” the aquarium for a few days. Then resume lighting at reduced levels and duration.

Low maintenance floating plants

If you wish to forgo the purist approach then the use of floating plants may represent a great way to get the benefits of plants without actually planting anything. Some aquarists may consider this cheating, and no longer call the aquarium a strictly plantless one, but the decision is yours. Considering the advantages and disadvantages of each approach, if you feel satisfied with using floating plants then it is an acceptable and low maintenance way to enjoy your tank.

Step two: making your plantless aquarium design look great

Once your aquarium is functioning smoothly without plants, it is time to consider how you can set up the tank to stop it looking so stark and barren.

The key to aquascaping successfully, is in paying more attention to your tank’s hardscape- the rocks, driftwood, sand or gravel and any ornaments that you use to give your tank its own unique identity. Providing a rocky background can be a great way to bring character to an aquarium. Many aquarists use plants to hide the unattractive equipment of their aquascaping job. In a plantless aquarium this is not an option.

Using rocks as decor

Rocks can make an excellent foundation for a plantless aquarium design, and owners of Malawi biotopes have been using them for years to great effect. Most Malawi biotopes are plantless by design because rocks are an integral part of the Malawi lake ecosystem. When setting up your tank using rocks, you will want to use many different shapes and sizes of rock, to mimic a natural looking environment.

Malawi aquarists emphasise height in their use of rocks. Not just selecting tall pieces of rock but actually stacking rocks on top of each other to achieve height. However, care must be taken that such structures are safe. Falling or toppling rocks can crack the glass and even land on fish.

Often, a rock-based plantless aquarium design will feature a very large centrepiece of some kind. A particularly ancient-looking stone of great size can lend an air of gravity to the entire tank and give you that zen-like sense of the sublime that makes plantless aquariums so special. Multiple rock formations can also be very interesting, especially in carefully laid scenic patterns.

Rocks, stones and pebbles can be constructed upon sand to make a desert like aquascape reminiscent of a real life desert. Stones and pebbles can also be used to form cave structures, valleys and hill formations. The possibilities are endless.

Making the most of driftwood

Driftwood is another incredibly popular element of plantless aquarium design. By layering choice branches of driftwood throughout your aquarium, you can achieve a natural beauty that reminds you of the jungle without needing any distracting greenery getting in the way. Amazon biotopes will frequently use driftwood and sometimes are plantless.

The key with layering your driftwood successfully is in finding suitably gnarled pieces of it. Straight driftwood can be used to great effect sometimes, but is better to used gnarled old branches that curve and twist. They can be used throughout the tank in an inspiring way. Rather than going for a centrepiece like you would with rocks, often the best approach for driftwood is to distribute your pieces naturally throughout the tank in order to mimic nature.

Other decorative items

Of course, there is no need to feel like you are limited to choosing between driftwood and rocks. These are just two of the most popular decorative items commonly used to great effect in world-class plantless aquariums. For your own plantless aquarium design, your imagination is the limit. Some aquarists enjoy putting model miniatures in their tanks, and others decorate theirs with hand-blown glass.

If you have an interesting, out-of-the-box idea for your plantless aquarium, you are encouraged to explore that idea. Many beautiful aquaria have been created around this concept: take that idea, put it in a box, fill the box with water and fish and enjoy your own unique plantless aquarium design. Examples being say stonehenge, the parthenon, the pyramids or Atlantis.
