Help PH 8.2 powder on corals!

Not sure if this has been mentioned, but make sure your Magnesium is up to snuff. Low mag can cause imbalance in alk/ca, which can affect pH.

Thanks Dakota. I had not heard that. My Mag was around 1000 last night. About 9 pm and I think that I heard that your Mag drops at night...?
I added a small 2 1/2ml of "ions" last night to bump up the level a little bit. (Mag supplement)
