Hello,
Ive been having problems with my pH lately since adding many sps over the last few months. I tested magnesium for the first time today, thinking it may be low, but it was just the opposite. Here are my current parameters.
salinity 1.026
pH 7.79
alk 9dkh
calcium 425
magnesium 1600
phosphate undetectable
nitrate undetectable
I have been using Seachem Reef Advantage Calcium in my top-off water which has a fixed amount of magnesium and strontium already included, so I suspect I will have to switch to a calcium chloride so the magnesium lowers to 1300 or so. Is the high magnesium depressing my pH? One more note I should add is that I use Korallin PO4 Minus (lanthium chloride I think) - could this have anything to do? :confused:
