All For Reef to kalk conversion?

[Randy Holmes-Farley]

But what is very low? I don’t know if I should start 400 ml per hr or what?

Just to reiterate more clearly; if you keep dosing the same AFR that keeps alk where you want it, then IMO it is a waste of effort to simply add kalkwasser since the amount you can add without alk rising more will be too small to be useful for pH.

That said, if you want to go ahead, I’d start by adding 0.5 dKH worth of kalkwasser per day and monitor the alk daily for a while. This calculator will help you know how much kalk (limewater) that is on your system:
