dclegern - I would start by upping your water changes, and before you do your changes use a turkey baster or small powerhead to blow the detritus off the rocks and get it into the water column so you can remove some of it with your water change. How deep is that crushed coral bed? I'm just curious, since I have heard from more than one source that cc is bad about trapping detritus and causing nuisance algae.

How old are your halide bulbs? Sometimes older bulbs can cause nuisance algae. And I still suspect that your detritus buildup is due to a lack of turbulent water movement in the tank. You might try relocating a couple of powerheads, or maybe using a small wavemaker.

Karin -"Just please don't ever get seahorses." That wasn't necessary. I have pipefish, and I am well aware of their feeding needs. The tank having the problem does not have pipefish, or seahorses, and additional food load right now will just make things worse.
