Is anyone using Tetra Lily Gro in their tanks? I used to have success with Tetra Lily Bloom but that product seems to have been discontinued. Now I'm considering Tetra Lily Gro. Does anyone have any reports about its effects on fish in the tank? How many tablets should I use for a 13x36 bed with an average of 3" of flourite? It's a 40-gallon tank.
