[quote author=Matt Rogers link=board=Newbie;num=1092322144;start=0#9 date=08/13/04 at 15:14:47]My diy rock is getting a lot of coralline and crawling with bugs now. It did take a long time to make (couple weeks playing around), longer to cure (couple months, didn't do enough water changes in the kiddie pool) and even longer to get things to grow on it. (close to a year, due to bad parameters in my tank until I got dosing down.) Now it looks great though and I am pretty proud of it. If you do it, get a masonary drill bit and drill the hell out of each rock. Makes it incredibly more realistic looking and more porous for bugs and bacteria.[/quote] How'd you get these critters growing on it?
