I want to get anacharis for my aquarium, but I'm not sure if I should. I know it's very cheap but then I never had luck with anacharis in the past. They seemed to just disintegrate in the water and turn brown. Well back then I never turned on my light for long periods of time (1.5 WPG). Should 1.5 WPG be good enough and that I put liquid supplement into the water?
