is it true that low levels of magnesium can lead to poor colors in sps corals? my alk and calcium are in line, but i dont test for magnesium, and im thinking its on the low side. recently ive been having some browning issues, and i dont know what to blame it on.
I've never seen low mag cause browning issues. My mg was at 900 for a long time before I caught it. None of my corals were brown at the time.
capn_hylinur Sometimes if you are pushing your ca reactor too hard it can cause lower tank pH. The only suggestion is to try and dose some kalk at night. I used to mix a teaspoon of kalk with a little ro/di water and just tossed it in the sump. I did that a few years back when I was having large pH fluctuations. The ultimate solution was to get a different ca reactor that didn't have to work so hard, but that's another story.
