Its a harsh dip but good for getting algaes and other stuff off of corals.

I brought my new corals home after the meet and did my Bayer dip. A few pieces from an acro frag broke off, unnoticed by me. They stayed in the bucket I was using for the dip for over half the day. I didn't notice them until I dumped the bucket in my bath tub. I scooped up the pieces, rinsed them, and mounted them in my tank. Polyps were out by the end of the lighting period. They look a little pale, but definitely still alive after hours in a Bayer dip!
