| This is where the plants and algae come into the equation, because nitrates are excellent plant food. (Algae are a basic form of plant life.) The plants remove the nitrates from the water to combine with carbon dioxide and sunlight to produce more plant. Fish such as koi graze constantly on the algae, and will eat some of the dead leaves that fall into the water, so the circle at this point is complete. for more info. please visit http://forum.californiawaterscapes.com |
