Don’t forget your Mg. Here’s a good read:

I had my Cal. levels accidentally high, and have been slowly dropping them over the course of the past 2 months. Corals and critters didn’t seem to mind, but:

Cal: 480 (now, was around 510)
Mg: 1350
dKH: 8-9
pH: 8.1-8.2
SG: 1.026, right on the money every time.

I replenish the evaporated water on a bi-daily basis, no ATO. I dose about a tablespoon of Reef Builder on a weekly basis to keep my dKH where it needs to be.

around 440 and 9 for me…
