Elodea: water plague or aquarium decoration?

Elodea, which is frequently found in ponds and aquariums, has generated a lot of discussion among fish hobbyists. This plant, which is well-known for growing quickly and having a lush green appearance, can either make your tank look better or turn into an invasive pest. Elodea is considered a valuable addition by some hobbyists because it offers fish habitat and natural beauty. It is a natural means of maintaining clean water due to its capacity to absorb excess nutrients.

However, Elodea can easily become an annoyance due to its rapid growth rate. It could take over your aquarium if it is not properly controlled, competing with other plants and clogging your tank. Because of its dual nature, Elodea can be both a benefit and a potential hazard for your aquarium. To assist you in determining whether Elodea is the best option for your aquatic setup, we’ll examine both sides of the argument in the article that follows.

Distribution

Elodea’s homeland is made up of slowly moving, stagnant bodies of water in both North and South America. Botanists were immediately interested in it after it happened to arrive in Europe by accident. The plant’s shoots ended up in the closest body of water after being used to adorn the Botanical Garden in St. Petersburg.

The shoots’ modesty allowed them to start growing actively, and they currently spread throughout Russia, all the way up to Lake Baikal.

Growing and care

Elodea grows up to two meters tall in the wild, with fragile, thick stems and green leaves that curl at the tips. Aquarium specimens are more ornamental and smaller in size; under bright light, their nearly transparent leaves have a noticeable metallic sheen. Although it doesn’t require much upkeep, the plant still needs certain minimal requirements.

Water parameters for ideal maintenance

Elodea prefers water that is between 17 and 24 degrees, or cool or room temperature; it dislikes water that is too warm or cold. Acidity and hardness essentially don’t matter. Any parameter that is stable and does not undergo abrupt changes can be adapted to by the plant.

One of the essential requirements is water filtration, though. Elodea is good at holding onto small particles and suspended matter, but as a result, its aesthetic qualities quickly fade. Although optional, CO2 supply is preferred for Elodea’s development.

When transferring Elodea to a new aquarium, only then should you pay attention to the water’s hardness and pH level. A large deviation from the original parameters will cause the plant to die and its leaves to literally dissolve.

Lighting requirements

Elodea requires 0.5 W/l of consistent, reasonably bright lighting for at least 10–12 hours every day. The leaves will start to rot and fall off in the absence of light, and the plant will grow much more slowly.

A well-lit plant can release oxygen and look presentable, which is why it can occasionally take the place of an aeration system.

Elodea parts have a rapid tendency to rot, degrade, and contaminate the aquarium. As a result, you must get rid of any cuttings, broken stems, and fallen leaves right away.

Requirements for soil and nutrient substrate

When growing Elodea, the soil’s quality is not very crucial. The plant takes up nutrients from the water through its leaves because its roots are weak. The substrate layer needs to be at least 2-3 cm thick in order for Elodea to take root properly. That is the only requirement.

Demanding of fertilizers

Furthermore, Elodea doesn’t require extra fertilizer. It feeds on the waste materials left over from fish and other living things.

Elodea can be turned into a delicacy and fed to goldfish or other vegetarian fish. The gluttony of the aquarium’s occupants can alter the appearance of the plant, which they will perceive as a source of nutrients from the juicy, delicate stems.

Reproduction

You must take a healthy, reasonably long (at least 20 cm) cutting in order to propagate Elodea. It is deeply planted and allowed to grow roots; eventually, these roots will cling to the soil. Even in situations where the shoots are merely placed on the water’s surface, they swiftly take root and grow.

Although elodea is sometimes thought of as a water scourge in aquariums, it can actually be a lovely and useful addition to your aquatic environment. Although Elodea can be difficult to control due to its rapid growth and ability to take over a tank, it also provides beneficial features like oxygenation, algae control, and fish habitat enrichment. By learning how to control its growth, you can transform this sometimes misinterpreted plant from an eyesore into a focal point of the arrangement in your aquarium.

Plant varieties

Elodea comes in about 20 species in the wild, but aquascapers are interested in four of them:

Elodea from Canada

The most prevalent species, which is cultivated in aquariums most of the time. The plant grows quickly and thrives in cool water under bright lighting. Its thick leaves curl along the central vein of its long stems.

Elodea with dense leaves

Large, roughly 5-cm-long leaves that range in color from light green to brilliant emerald are situated atop the plant’s stem, which resembles a cord. Adapts well to CO2 supply, loves cool water, and is insensitive to hardness and acidity.

Dense Elodea

Its leaves are a deeper shade than those of other plant varieties, and its stem is relatively short. Planting the variety in bunches of ten to fifteen branches is advised because they create a hedge and have a very unique appearance.

Crispa Elodea

The crispa has thinner, more wavy leaves than the Canadian elodea variety. It also blooms more frequently, is kept in warm water, and is highly erratic.

Nearly all elodea species are invasive, meaning they can have an impact on the aquarium’s ecology due to their rapid growth.

Since elodea is only found in freshwater environments, even trace amounts of salt are harmful to the plant. If ichthyophthirius needs to be treated, which is done with saline solutions, the plant needs to be taken out of the aquarium.

Elodea in aquascaping

The plant appears well against the aquarium’s background. Nothing is left. But Elodea needs frequent trimming because, if neglected, it soon becomes a thick, messy mass.

You can use it to create compositions by attaching segments of a lengthy trunk in between ornaments, stones, and other components. They are able to establish themselves here and produce new branches.

According to some, eloxea juice is toxic to fish and finicky plants; therefore, in order to prevent poisoning aquarium occupants, specimens must be taken out of the water prior to trimming, and the process must be completed elsewhere. Most aquascapers who thin out the plant’s thickets in the aquarium do not agree with this statement.

Elodea, which aquarium enthusiasts debate a lot, can be a great addition to your aquatic setup. Although some see it as a problematic water plague, when properly managed, its advantages can outweigh its drawbacks. Fish and other aquatic life benefit from this plant’s balanced and healthy environment, which is maintained by its quick growth and capacity to absorb excess nutrients.

To stop Elodea from taking over the tank, though, it must be kept in check. To guarantee that it becomes a lovely and useful addition rather than a bother, regular pruning and appropriate placement are important. You can take advantage of its useful features and visual appeal by finding the ideal balance, making it an asset to your aquarium rather than a cause for aggravation.

To sum up, how you handle Elodea will determine whether it becomes a decoration or a challenge. This adaptable plant is a valuable addition to any aquatic setup because it can improve the aesthetics and health of your aquarium with careful maintenance.
