well, the buce, anubias ferns and mossss don’t like much light and co2 is kinda unnecessary and lost on them. they aren’t fast growers so they just get alaged on. I would only use them in a low tech tank with low light. it’s a balancing act with these high tech tanks to control nutrients, co2, light and algae. i think it’s hard then a coral reef aquarium to get it really perfect. i’m not an expert, just my two cents. maybe lower the light intensity a bit. cut the photo period down to six hours. Even in my high tech tank i only ran the light six hours, down from eight to limit algae growth. the carpet still grew fine. my crypts never grew.
