I was planning to have my new 75g reef be bare bottom to better maintain the water conditon for a mainly sps tank. But every person at my local fish stores are all against them and say they make the water harder to maintain and go on and on about how fish aren't happy in a bare bottom tank and when I ask why they have little to say other then I won't have benifical bacteria or live food for fish. I feel as though this is untrue. Why would it matter if there was live food in the sand? The only live food I care about are pods and they will grow in my fuge. And I know benifical bacteria will grow in my rocks. I think these are all old guys in the hobby that still like the old ways. I mean they all still try and push mh lights and wet dry filters. Am I being nieve in think bare bottom is the way to go? Please please give me your opinions.
