Hi,
J&L carries Chemi-clear. Its a potent form of an oxidizer and it seems to work well. Keep in mind that oxidizers will quickly convert your water from a nutrient rich...to nutrient less. So, if you have corals that thrive on the high nutrient water...the quick change to nutrientless water may be a problem (SPS are a prime example). I have used it before and it seems to work, but I would keep a close eye on overflowing skimmers (yah...happen to me
