This topic is beaten to death on this website. If its a BB display with a remote DSB then thats what it is!!!. Will it reduce nitrates? most likely since it will provide an anaerobic area for the nitrogen cycle to take place and Nitrogen gas will escape the system. Will it reduce phosphates? Seems to be a hot topic with many armchair quarterbacks and little scientific proof of the mechanisms occuring, the N cycle is pretty well know, the PO4 cycle is in a saltwater solution is subject of much debate among scientists/ experts as it is a highly reactive molecule and can follow many "paths" Does either substrate/lack of substrate make the corals grow without growing excess micro-algae? Thats up to the husbandry skills of the reefkeeper. Did I miss any beat to death DSB vs BB arguments?
