I have not done any icp tests, idk where to find any in my country. And arent they really expensive?At your current levels it's not urgently bad but high magnesium can hurt inverts over time. You want around 1400 mag and cal 420 to 450. I use coral pro salt also and it works well to maintain numbers. Alk and cal become necessary to dose as you get enough corals which I'm sure you know. Magnesium only depletes at 1/10th the rate of cal and alk so it is fine with weekly water changes maybe a small hand dose weekly.
Have you done a recent ICP test to look at everything?

already knows all that stuff, but your right some people let their salinity and temp go all over which can be ok for some systems but not so much for others. Good thinking start with the simple stuff first and cross them off the list if thats not it!
))), Im asking what are the common reactions of the corals to high salinity
