It's starting to cover my new frags and my fungia plate...darnit! [/quote] BINGO, you've found out what black Powder does for a reef. IMO disconinue use, call it a loss, and flush the junk. Any product that does now list the ingredients, be very skeptical of. I've used all MS products, all are snake oil IMO. Slick packaging, yup!
