another day, another problem...
my top-off system decided to go nuts and dump all of the water (thankfully only about 4 gals) into my sump. My top-off water contains Seachem Reef Complete (with magnesium and strontium).
Needless to say, my calcium is above 500ppm. My pH has dropped to 7.8 (yikes) but my alk is ok at 9dkh (typical). Salinity is lower than normal from all the fresh water, but not much. So, does this make sense? I would have thought my alk would have dropped to cause the pH drop - am I wrong?
So to sum up params:
Calcium 500ppm+
Alk 9dkh
pH 7.8
Salinity 1.025
Nitrates 0
Phosphates 0
I dont test magnesium and strontium, could excess of these lower pH???
