Has anyone had Tropic Marin Pro mix with high mag and cal? Could it be from not mixing the salt (I’m getting towards the bottom of the box so maybe it settled?) Salinity is 35 (with calibrated hanna tester) but mag is testing 1800+ and ca is 600+. I tested with another tank that I haven’t done a water change on with this new box of salt and Ca and Mg are in a normal range which rules out the testers.. RODI water is testing at 0 TDS.
I assumed I had overdosed AFR or something so I did a series of big water changes with no success, so thought to test freshly mixed water and got the same result. Both Ca and Mg testers are Hanna as well.
Other params:
Nitrates: 11
Phosphates: .05
Alk: 9.2
Temp: 78
Could the high Ca and Mg be the cause of some of the coral death i’m seeing? I have a mushroom rock that was previously thriving and now has a lot of tissue loss. :’(
