Hornwort is not planted in the ground.
It can be pressed with a stone or tied to a suction cup and stuck to the glass. Or you can leave it floating.
The thin leaves of hornwort serve as a good shelter for small aquarium fish and fry, among which some fish can lay eggs, so the plant is also often placed in spawning grounds, where it serves as an additional source of oxygen and shelter.
Lighting: twelve-hour daylight is needed, but direct sunlight is destructive for the plant.
Requirements for water in the aquarium: temperature – 24-28 ºC, pH – 6.0-8.0, hardness can be any.
There should be no copper impurities in the water.
Feeding: not needed.
It is necessary to change 50% of the water once a week, and if the plants are planted very densely, it is better once every five days.
Also, with replacements, excess udo is carried away, and they need to be given in excess when there are dense thickets of plants.
It is also very important to siphon the bottom in aquariums with plants.
After 2-3 months of the aquarium's life, this becomes necessary.
If there is not enough light, submerged Hornwort will not thrive.
This will lead to poor growth. Fungi and bacteria can feed on plant tissue, which is common in plants grown in shaded areas.
When plants receive too little sunlight, they become spindly.
