| Sorcerer,
I've used Chemi-clean in the past for an annoying cycano outbreak. Worked great, no problems what so ever. I will be honest, the tank didnt have anything wildly sensitive in it at the time though. I wouldnt hesitate to use it again either. The LFS that I go to here in St louis reccommended it, since the owner (the person I was speaking to) uses it on her tank at home, which does have alot of SPS and other delicate critters.
