calc is right around where it should be.
alk is still a little high. im not sure how sensitive sps corals are to alk, though, so I don't know if that is your problem or not. 8-12 is supposed to be where you're shooting for and you're close to it, but remember that most natural coral reef systems have alk in the 6-8 range.
mag is ok....a little on the low side but not dangerous. Generally want it to be 1250-1350. This definitely isn't your problem.
