Succeed with aquarium plants
How to succeed with aquarium plants: a guide to aquarium plant care
While the beginning aquarist spends a great deal of time learning how to tend to fish and give them an environment in which they can thrive, aquarium plant care is, by comparison, a subject that is rarely given the full attention it deserves. Keeping your plants happy is just as important as keeping your fish happy, though, since the two will live in coexistence in the closed ecosystem that your fish tank provides.
You can’t just place plants in your aquarium and expect them to thrive or even stay alive. You must pay attention to the lighting, water conditions and the fertilisation needs of the plants.
Choosing the right plants for your aquarium
The most important aspect of aquarium plant care is: choosing the right plants for your aquarium. The right choice here can make the rest of your live plant experience a pleasure by providing a beautiful environment for your tank while controlling algae and absorbing unwanted ammonia and nitrates.
There are scores of plant species that, though undoubtedly beautiful, are very sensitive to water conditions, require specialized CO2 systems, or need extra lights in order to flourish. At the same time however, there are plenty of hardy, attractive plants that provide all the benefits that you expect from aquarium plants without the extra hassle.
A list of some of the best options for your first aquarium plants for the beginner are as follows:
• Java Moss. This unassuming plant is one of the most popular aquarium plants worldwide for a number of reasons. It thrives in a variety of environments, offers lots of convenient hiding places for fish and their fry, and offers simple, beautiful decoration for aquarium owners.
It can be tied to rocks or driftwood with fishing line, or left to float naturally through the tank. Java moss requires very little maintenance; only some occasional trimming when it gets too thick.
• Amazon Sword. This plant can reach a great size, even under low lighting. Evidently, this plant is ideal for large tanks, and may require fertilizer tablets because of the fact that it is a root-feeding plant.
• Java Fern. This plant can survive in nearly any aquarium, and is very forgiving when it comes to water quality and light. Even goldfish that regularly eat aquarium plants will generally leave Java fern alone.
• Valisneria. This plant will feel right at home in a variety of aquariums, although some hungry fish might decide to snack on it. Vallisneria spiralis is usually singled out as being one of the best varieties for aquarium plant care beginners.
• Anubias. This is one of the only underwater plants that actually prefers low lighting, and to make it even more attractive to aquarium owners, herbivore fish tend to leave it alone.
While many other specialty plants can provide a fun and challenging experience for live plant enthusiasts, any of the plants listed above make an excellent introduction to the world of aquarium plant care.
Lighting for your aquarium plants
Once you have chosen which species of plants you would like to keep in your tank, you must consider your lighting setup in order to give the plants the correct environment in which they can thrive. In general, your aquarium plants will do best with day and night cycles of 12 hours each.
The duration of the lighting period is important, but you must also examine the type of light that you use in your aquarium. Lights designed for aquarium plant care are notably different than average fluorescent lights, and you will need to make sure that yours carry a suitable Kelvin rating, among other characteristics.
• The Kelvin rating refers to the spectrum of light that the bulb emits, commonly referred to as the, “temperature” of the light.
• Most plants reject green and yellow light while absorbing red and blue light, as well as light on the ultraviolet scale. In terms of the Kelvin rating, this means that you should provide full-spectrum lighting between 5500 K and 7500 K for most tropical plants, including as the ones listed above.
• LED lights often offer the best combination of low power consumption with light intensity, ease of installation, and price. Make sure to purchase quality LED lights, however, as the market is full of low-quality options not suitable for aquarium plant care.
Following these guidelines will help ensure that your plants grow large and healthy, although providing them with ample light will make your plants hungry for the nutrients they need to thrive.
Feeding your plants: fertilizing your substrate
Once you have developed your lighting setup properly, it is time to consider the fertilizer and nutrients that your plants will need. Many waterborne fertilizers will provide the boost that you need to get your plants strong and healthy quickly— especially in the beginning stages of aquarium plant care.
You should be aware that many of these store bought fertilizers, while very good for plants, contain nitrates and other ingredients that are poisonous for your fish. Most fish can tolerate small amounts, but over exposure to fertilizer will kill them, so use these fertilizers with care.
But better still use a substrate fertilizer for rooted plants like the Amazon Sword. They come in tablet form. These tablets need to be pushed into the substrate directly to the root base of the plant. In this way they directly feed the plant rather than into the water in general.
Choosing between gravel or soil
While soil is a much more natural substrate for aquarium plant care, it is notably more complex to keep in optimal condition. Soils are generally reserved for experienced aquatic gardeners who wish to grow particularly difficult underwater plants.
If you introduce soil into your tank it can affect the water quality for your fish.
Therefore, gravel is generally recommended as the safest option. You can always add soil in separate pots if you wish to experiment later on.
The benefits of potting your plants
One of the key benefits to be realised by potting your plants, apart from being able to use soil without disturbing your tank’s existing substrate, is that your pots will also protect the plants. Potted plants have a secure location from which they can grow, and this can help keep them alive when nosey fish want to dig around their roots.
While gravel may be an acceptable substrate for beginning aquarium plant care, you may find that some of your more active fish seem intent on overturning the rocks and digging into the roots of your plants, harming or possibly killing them in the process. Potted plants combat this behaviour by offering your fish very little space in which they can satisfy their curiosity or hunger.
Reproducing aquarium plants for fun and profit
If you give enough space, nutrients, and lights to your plants, you may find that they begin to propagate and reproduce. A vast majority of these plants reproduce asexually, meaning that, if the conditions are healthy, they will simply begin sprouting new individual plants without your intervention at all.
Some species of plant, however, may need your help reproducing, and often it is worthwhile to expend the effort— aquarium pants, just like fish, can be bred and sold for profit. Seeded plants like lilies are notably more complicated to breed, and tend to command higher prices than their asexual cousins:
• A plant cutting is exactly what it sounds like: a segment of the parent plants’ stem, cut and replanted into the substrate of the aquarium or pot. In most cases, these cuttings will grow their own roots and turn into full-fledged individual plants over time.
• Plants that have seeds will need to be sexed and paired in order to propagate successfully. The two parent plants will need to be flowering above the surface and then have their pollen transferred from one to the other. If pollination is successful, seeds will be produced and those need to planted in damp soil as quickly as possible.
Over time, you should be able to grow a healthy collection of extra plants using these aquarium plant care methods, and you can then begin to sell to or swap with other local aquarists either through the help of your local fish store or directly using an Internet classifieds website to find customers.
