    What is the eeeek for? When I had fish only and decorative coral (no live rock) I did a 30% change every 6 weeks, when I went to FOWLR I changed 25% every 5 weeks. After converting to fish, live rock, coral and sump, I change 10% once a month. It hasn't mattered at all. I will say I change 30% every other week for my 14 gal. Biocube as I don't run a protein skimmer or phosphate reactor for it.
