I have a 200 gallon mixed reef. Trying to get more into sps corals. I have been running bio pellets for some time now and I still can't get my nitrates down to zero. I'm thinking of removing the bio pellets, and making a sulfur denitrator to help with the nitrate problem. But then again, I never read here on the SPS forum that anyone runs one.
