Just reading along, someone mentioned DOC, I'm agreeing with this. Fits well with your SPS decline at the 1.5 year mark. The stuff you have can probably tolerate slightly higher DOC, at least we know the clams and BTA can, the carpet nem is a little bit of a surprise to me but I'm not real familiar with them. Didn't see what the flow of your return pump was, I had similar problems except I was totally over run with hair algae and doubled the tank turnover, got the waste out of the tank before it could settle into sand and rocks and instead into sump where skimmer could get it and upgraded my crappy skimmer(not saying yours is). Anytime I see a tang in a small tank I'm thinking DOC, those things are poop machines. First person to make a DOC test for this hobby is going to make a killing.
