I don't know what happened but my mag dropped to 1150 so I started dosing Mg Cl
and have been raising it by about 100 ppm
a day. Since I've started a big acro's bleached out, a little frag of monti digitata (but it fell off a shelf and landed in a LPS
so that could have done it) and about a 1/4 of a favia brain. All within a week of each other.
I have 0 phosphates and 0 nitrates. Cal is 420 and Alk
Another thought is I've started fragging and I fragged a green slimer sps
. Right after I fragged it it released a TON of slime, could that cause some coral to bleach?
Everything else in the tank is rockin. The only changes has been the fragging and the mag increase.
