I have a DSB and like it especially for it's NNR ability and the accompanying diversity of infauna which not only helps keep the top layer well oxygenated but also makes it work properly, but acquiring the infauna can be difficult, it won't just migrate from the LR as many people think. Also having good flow is very important so that detritus won't accumulate in certain spots. I think that people tend to overfeed and overpopulate their tanks and think the DSB will perform miracles, it has it's limits.


My main concern with the DSB is that PO4 will eventually to bind to it and once saturated will cause algae problems and possibly inhibit calcification of Stony Corals. My tank is only a 93 gallon so if I need to replace it it'll be a PITA but doable but in a larger tank may be an enormous task.
