After reading a bit on the peroxide, I don't think i like the consequences of using it. I do have the Mag up to 1500 now, no change in my cal alk or pH. I have been brushing the dino off of my coral, I am concerned especially with my pocillopora since i haven't seen any polyp extension on it for quite some time now. Is using a tooth brush too much for the coral on a daily basis? Any other steps i should be taking to fight this crap?
