Calcium Sudden Drop

Zatar1974 · Jan 21, 2021

My calcium dropped from 430 to 330 overnight. Only thing I did was add KoralRecover...but how would that reduce my calcium???

If I recall how it works is: it adds a coating to damaged corals to help them recover. Could this coating be effecting your test kit results?

That is test error somehow. It is chemically impossible for calcium to drop that much in a reef aquarium unless to dropped by 14 dKH. Presumably that didn't happen.

Thanks... I recalibrated my system and back to norma.
