Andrew!

Christy, I feel for you. How old is the tank? Is it possible you are going through an algae cycle? Somewhere you have more nutrients coming in than are being exported.

The things I'd look at are feedings, protein skimming, water source and circulation. Keep your skimmer clean (everyday for the next while), cut back on feedings, remove what you can of the algae (your fish will be fine), test your source water and do some water changes. A phosphate remover may be an idea. You may have to increase your clean-up crew and consider adding a conch or maybe a urchin if the problem persists (I have no experience with either but have heard positive things). Dale said he'd had some luck with a bi-colour blenny Ecsenius bicolor and microalgae. Don't give up.
