Hello my name is john and i have 2 D. Aratus that I got about two weeks ago, after looking at everyones projects on here, I want to start my own.I haven't decided whether or not to do some type of waterfall/flow or to do a corner of water with fish. Any suggestions will help! What things will I need? What small pump is best? Anything? And what is the plastic stuff ppl are using for false bottoms that has the squares(they put it on top of PVC)? Thanks hope I get some help and tips and anything lol
