Corals Dying - Calcium

[asylumdown]

I should also ask, why were you dosing calcium at the rate you were dosing, and what concentration do you mix your calcium solution to (1 cup per gallon or...)? Was it low when you started? You should be tuning the amount you dose calcium to match the rate at which it's being consumed, as determined over a couple of weeks of regular testing and adjusting. If you're not mxing your dosing solution to the same concentration each time you refill it, you'd then need to re-tune your doser when the reservoir was replenished. Was 40 seconds 3 times a day a number that you determined to the be the right number to maintain your levels where you wanted them?
