How have you got these plants to grow so well? what lighting are you using? I have a new 2'x2'x2' tank that I have just planted (no fish in it yet) but in the past I have not had much success with plants.
Also does anyone know what I can do about really soft water, The tap water I use (from town supply) is very soft then stays that way when in the aquarium, this I think will be fine for the discus I will eventually put in there and for the amazon type environment I'm trying to create but I worry that it will get even softer, I don't know much about hardness only how to test for it.
