Question on Difficulty Raising Calcium in 33 gallon tank..

[Aqua Man]

I'm assuming my coral isn't too upset since alkalinity is testing within the target range for most of the day while I'm actively dosing. These mornings are a concern

If your coral look normal I would not worry much. Since alk and cal gets used during the day, having low numbers in the morning before dosing seems normal. I’ve had alk drop low, 6.5 and didn’t notice any issues.
