Water Plants
On the surface and in the water

 
 


FLOATING PLANTS

These plants require no planting. These plants float at the surface of the water, with their roots hanging free to absorb nutrients and provide shade and cover for fish. Floating plants desire tropical temperatures and cannot tolerate a frost.

OXYGENATING PLANTS

Underwater oxygenating plants may be added to aid in maintaining clean and pure water. These plants aid in the prevention of algae growth through absorption of nutrients and carbon dioxide through their leaves. They complete with single-cell algae that cause green water. They also provide a place for fish to spawn and trap debris. Oxygenating plants can be allowed to float freely or be anchored in pots using gravel to hold them in place. The use of soil for planting is counterproductive, as it adds nutrients you are trying to remove with the plants. Do not fertilize for the same reason. A one gallon pot is recommended. Completely submerge these plants to a depth of at least 12."
