Thanks so much for the input on my last post regarding using sand or not using sand in a reef tank. I learned a lot and have acquired the knowledge I need to move forward. That being said, I am leaning towards either going with no sand at all, or a very shallow sand bed....basically a light dusting of sand on the bottom for visual effect. Here are the questions..... 1. If I go with NO SAND, how much flow do I need to have in a tank of SPS, LPS, Anenome? Or to put it another way, do I have enough flow? (I have a 240 gallon tank with 2400 gph overflows and two vortechs.) 2. If I go with NO SAND, is my skimmer adequate to handle the load? I have a turbofloater 5000 shorty by aqua medic. If the link does not work please go to the aqua medic website.... protein skimmer link 3. Can you have anenome with no sand? 4. If I go with SSB (shallow sand bed), will I have the same issues with blowing sand that I might have with a regular sand bed? In other words, is there any advantage to having a having a SSB over a DSB as it pertains to blowing sand? 5. Is the idea of a SSB kinda dumb? Is it all or nothing? Is there a middle ground (SSB) or did I just make this up?
