I have herd of some reefers taking it up to 2000 pp to get rid of bropis. I would not do any thing fast to correct the problem or you will shock your corals. I ther is damage it is done already. Good luck
I don't think so. The only problem is if you add anything else that reacts with Magnesium then your levels can get all outta whack. As shaper said. Becareful not to shock your corals, if you do a water change and it changes the composition too much, they won't be happy.
