Hygrophil Multiseed (Hygrophila polysprema) – aquarium plant Hygrophil of the Acanthus family (Acanthaceae). Also, this plant is called Indian star or Bog.
In nature, it occurs in swampy areas of Southeast Asia.
Hygrophil Multiseed has light green oval leaves and rather long stems. There are three garden species: The first has a lanceolate and rounded leaves, painted in a light green color. The second is “Rosanerving” with exactly the same leaves, but with crimson, yellow or orange veins.
The color of the veins and the leaves of the plant depend on the lighting in the aquarium. In the third species, the leaves are long, narrow and pointed, differing in red-brown color.
Hygrophil Multiseed feels good in aquarium of any size, placed in the background, it grows evenly throughout the year.
Hygrophilus can be kept in a tropical aquarium with a water temperature of 24-28 ° C, and if it is below 22 ° C, the growth of the plant slows down. Hygrophil content requires soft and slightly acidic water.
If the water hardness exceeds 8 °, then the growth slows down, the upper leaflets are crushed, and the lower ones disintegrate. It is necessary to regularly replace water in aquarium.
Lighting it is necessary intensive, for this you can use both natural and artificial. If the sun’s rays fall directly on bog, then he needs shading.
To create artificial light, it is best to use fluorescent lamps of category LB at the rate of 0.4-0.5 W per 1 liter of aquarium volume. You can use and incandescent bulbs, their power should be three times more.
The light day should be at least 12 hours otherwise the leaves of the plant are crushed, and the stem will stretch. As the soil suitable lightly ground from small pebbles or coarse sand.
Naturally silted soil provides the plant with all nutrients. If aquarium plants grow in large quantities, then they need a complex of mineral fertilizers, which are applied daily when changing water at the rate of 1.5-2 grams per 10 liters of water.
Breeding Hygrophilous multiseed occurs by cutting the stem. The stem, having 4-5 leaf whorls, is planted in the ground, while the lower leaves are dropping.
Roots develop quickly. In a floating state, the plant is not recommended to grow, because in this state the leaves are shallow, the growth slows down, and the roots develop poorly.
