Couple questions.... anyone ever do heavy planting with peacocks (not bass). Tried it once before but I had a few Vic. Haps and some elec. bl. joh. in to toss it up but Once I would plant it heavy things would be torn up in a month. Do you have to plant way before you put fish back in?? Is gravel substrate fine?? I looked at some of my old pictures and the real plants look soooo much nicer but I'd like to do it again. One problem being....how much are the CO2 pumps? I'd rather stay away from that. Does the CO2 present problems for night time?? Shouldnt it be shut off at night? A couple of you guys had amazing planted aquariums.
