I removed all of my blue leg hermit crabs from my main tank and went with a snail only CUC after this I noticed GHA popping up all over my tank. It was a slow process so I did not make the association. I manually removed as much as I could a few weeks ago but it started slowly coming back. At the suggestion of my LFS I just purchased a couple of dozen red leg hermit crabs. I put them in my QT that had a couple of GHA covered rocks and they wiped them spotless in 5 days. I wish I took before and after pictures. The rocks literally had a two inch carpet of the stuff. I originally removed the crabs because they kept stealing food from my coral but my fish and cleaner shrimp do this anyway. If you can put up with them killing your snails and stealing your coral's food it may be worth it. I can't get them out of QT and into my main tank quick enough. 5 weeks to go...
