Levels way off again, help update
Water change Sunday, approx 25%, salinty 1.023-1.024, temp 82.
Mondays diagnostics: Calcium=220 ppm, Alk=2.5 meq/L, Ph=8.4
Added 40ml calcium,
Added 7 tbs CaCO2: 1 tbs CaCO to add Alk and
bring PH down.
Tuesday diagnostics: Calcium=160 ppm, Alk=7.0 Meq/L, Ph-8.6
Added the same dosage above.
What the heck is going on in my tank? 40ml of Calcium suppliment should bring it up from 220 to 300 no problem, but it went down! Why is my Ph so high? I need advice, my hard corals, zoos and anemones are suffering.
