Kreeger1 - yes that is the problem "Nitrates". They will get you at one time or another. The problem with smaller systems as I and others have experienced is the buildup of nitrates. These nitrates are not easy to get rid of once high levels have been found. I'm installing a RDSB to fight this and the hope is keep my nitrates at a reasonable level. I really feel that installing a RDSB on smaller tanks could really help fight this buildup and if it's a species only tank might help us keep these corals long term. For me this is just a test to see if it works as we still do not have the knowledge to keep these gorgonians alive for any length of time - flow, food etc.
