I had been a bit delinquent in recalibrating my trident salinity probe, Hanna salinity probe and refractometer. Once I did it, I realized they were all off and my water was running about 37.4 salinity Instead of 35 where I wanted it. I started gradually bringing it down to 35 over about 10 days. What I’ve noticed since doing that is my Alkalinity has risen from 8.0 up to 8.4, Ca has dropped from 450 to 390 and Mag has dropped from 1470 to 1390 very quickly after I made the adjustment.
Is there a tight relationship between salinity level and the three Alk, Ca and Mag causing this, or would correcting my salinity make it so consumption of the other three to start changing so quickly? I’m not trying to chase numbers, but to see such a quick change in everything worries me.
I do auto water change daily (2 gal/day for total water volume is about 180 gal), dose 30ml Alk, 30ml Ca and 10ml Mag daily. Tank is SPS dominate.
PH 8.1-8.3, temp 79-80, NO3 14.5, PO4 varies 0.1-0.2
