Little help?
 

I'm having a problem with some of my corals in the last couple of days. It looks like they are loosing their polyps. The only thing I have changed in the last while is I bought some Kent Liquid Reactor and Coral Frenzy and am having a hard time dosing with the liquid reactor. I find I still have to use Seachem liquid calcium and Randy's Alk recipe. What does Alk burn look like. I don't think it is RB or AEFW. So far there is a stylophora I picked up from marc (superfudge) a green humilis and a monti digi. All the symptoms are the same. Loss of polyps. Kind of like they got burnt.

anyone?
