Using Land Plants in Tanks
There are a number of land plants that will do very well emersed in an aquarium. I have various species of Aglaonema, Pothos, Nephthytis and Philodendron in my larger tanks. Kind of a biotope/terraphyte effect. Peace lily and varieties of Impatiens will work too.
You just have to remove the plant from the pot and rinse all the potting mixture from the roots. Emerse the roots, but keep the leaves above the water to take in CO2 from the air in the room.
The roots take in the nitrogens produced by the fish and the tank water stays pure. I just replace the tank water lost to evaporation.
Really reduces the water changes.
