I haven't tested my Mg for a while because I dose reef fusion which has calcium and mg in the same bottle. I tested it today with Salifert and I got around 1800 (1.2ml). My calcium was creping up a little while ago, so I assume that's why the Mg is high.
The reason I ask is because I suddenly lose seemingly healthy SPS corals. My birdsnests will grow like weeds for months, then suddenly stop opening and die. My favia is also not doing well, but I think that's because I had a rogue emerald crab picking at it. LPS corals, chalice, zoas all seem fine.
