Never been one for remembering plant names but, historically, every floating plant I've tried (all 2 or 3 of them) has gone mental and completely taken over the water surface.. are there any that don't?
This is a nutrient effect, it is telling you that your tank water is high in the macro-nutrients (N, P & K) that fuel plant growth. Because the leaves of the plants are floating they have access to atmospheric CO2, and because they are right up by the light they have a lot of PAR (Photosynthetically Active Radiation) reaching them.every floating plant I've tried (all 2 or 3 of them) has gone mental and completely taken over the water surface.. are there any that don't
Yes, as soon as any green part of the plant is above the surface it has access to atmospheric CO2 (at about 350 ppm CO2) compared to the ambient 2 to 5ppm in the water.Is it right that floating plants can make use of CO2 more because they float on the surface. I read the closer the plants are to the surface the more they can access CO2.
