Hygrophila polyspermous (Hygrophila polysperma)
Hygrophilus or Indian Elodea is an aquarium plant that is ideal for beginner aquarists. And all because it is one of the most hardy and common on sale.
Hygrophila polysperma was imported from Asia, but is also found in China, India, the USA and others. It is found in many reservoirs, rivers, lakes and is considered a weed.
Hygrophil feels good in water with any chemical composition and can withstand various temperature fluctuations.
It has become an aquarium plant since 1945. This is a creeping alga with a long stalk 30 to 40 cm long. It has pointed leaves, up to 1.5 cm wide and up to 8 cm long, which are symmetrically opposite each other. Their color can be either pale green, or brownish and reddish, it will depend on the lighting. It blooms with small pale blue flowers. Grows completely submerged in water or slightly protruding from the water.
Maintenance and care
Hygrophilus multi-seeded can grow in an aquarium with a variety of conditions and does not require special care. You can optionally supply CO2, but it must be borne in mind that then, the plant will grow very rapidly. Therefore, it is better to add carbon dioxide if the rest of the green spaces in the aquarium require it. It can be additionally fertilized with microelements, it will be useful for all aquarium plants. It also does not need additional lighting; it does not affect growth in any way. But in order for the leaves to be more saturated in color, it is better to make additional lighting.
Any substrate is suitable as soil, it can be either coarse pebbles or fine river sand. And all because the plant takes micronutrients from water, and not from the soil. If planted in the sand, then it is necessary to additionally weight something on top, until the hygrophil is not accustomed, it takes no more than a week.
Water can be any soft or hard with a pH level of 4 to 8. The optimum water temperature is from 17 to 30 0FROM.
Hygrophilia needs regular pruning, this will help slow its growth so that the plant does not fill the entire aquarium, and besides, it will improve the appearance.
Like many other climbing plants, Hygrophila polysperma propagates by cuttings. To do this, cut the top by 5-10 cm and plant it in the ground. And after 7-10 days, the sprout will take root and begin to grow actively. Hygrophilia can multiply even from one leaf, so if you want to plant several plants at once from one branch, you need to divide it into several parts and plant each of them. But you need to take this carefully, since the multi-seed hygrophilic belongs to weeds, therefore it grows very quickly, because of this it crowds out all nearby plants and fills the entire space. Most aquarium fish and snails are not interested in this alga and do not want to eat it. However, if there are cichlids and eternally hungry goldfish in the aquarium, they will not refuse such a treat, and if not, they simply dig a hygrophil from the ground. Well, the rest is complete freedom of choice.
In most cases, aquarists plant a multi-seeded hygrophil as a background plant, medium or background. But it is practically not used to create aquascape, due to its rapidly growing capacity, it can occupy all the space in the aquarium in a short period, especially if there is good lighting and enough nutrients. In addition, it can be used as a floating plant, a hygrophil will also feel great.
