Water lilies in the Nymphaeaceae family. Homeland: the parts of North America in the southeast.

A very lovely plant that aquarists hardly ever find. It grows into a long, creeping rhizome from which delicate, large, corrugated, arrow-shaped leaves that are up to 30-35 cm high and have beautiful vein patterns emerge. The leaves are a light green color. The plant is positioned in the aquarium’s center and in the middle of the space. It fits in a large or medium-sized container. The plant is comparatively uncommon because of its slow growth, certain maintenance requirements, and challenges with reproduction. It grows continuously for the entire year.
The only aquarium where the water lily should be kept is a tropical one with a minimum temperature of 24 °C. Its growth is greatly hindered in colder water. The plant grows best in water that has a hardness of 6–12 ° and a pH of 6.5–7.5, which is almost neutral. The aquarium shouldn’t be made to have a strong water current. The upkeep of the water’s cleanliness requires special consideration. The water lily’s condition deteriorates dramatically when organic and mineral particles settle on its leaves, killing the delicate leaves. Three to four water changes per month are recommended.
It is best to have the brightest possible lighting. Usually, a plant needs more natural light than what is allowed to enter the space through the window. For it, diffused sunlight is very beneficial. Additional artificial lighting is essential.
Fluorescent lights need to have a minimum power of 0.4 W for every liter of aquarium capacity. Adding more light from incandescent lamps is a great way to boost the spectrum’s red-orange ray proportion. Twelve to fourteen hours should pass during the day.
Nutritious soil is necessary for growing water lilies. Make sure to incorporate charcoal and clay into the newly planted soil. The silt that has built up in the soil will eventually be sufficient to nourish the plant. Periodically cleaning the soil with a siphon is required if there is an excessive buildup of silt. While the type of substrate is not very important, a combination of pebbles and coarse sand is ideal. The plant needs a soil layer that is at least 7 cm thick because it grows a strong root system.
The water lily is propagated in an aquarium vegetatively, separating its terminal part with a rosette of leaves and a root lobe from a sufficiently developed old rhizome. In this case, the plant gets sick for quite a long time and stops growing. You should not separate several parts of the rhizome, this can lead to rotting of the rhizome and the death of even a very large and strong plant. If signs of rotting of the rhizome appear, the rotten tissue should be removed, and the healthy part should be treated with a pink solution of potassium permanganate or a strong peat decoction. After this, the plant is planted in the soil, where charcoal must be added.
