I don't use DSB's any more. Right now my tank is bare bottom, but I am going to use a combination of Thorite cement and live rock fragments to produce a molded rock bottom for my 75, and for the 300 gal tank I am ordering in a few months. I can keep the current as vicious as I want hehehe since the corals I will have in there appreciate that sort of environ. No need to state my reasons...Troy just hinted at some research the interested party could do...Anthony Calfo's book details some good plans for denitrification that negate the need for a DSB, and you still get all the benefits. But aside from that I am tired of the look. How frequently on the reefs do you find little patches of sand with a couple of large rocks with corals sprinkled all over them like fruit salad? Not too often. Large corals, small fish. Expanses of sand, large rock and cliff formations.
