My calcium keeps dropping to 360. I bring it back up to 410 over the course of a few days, and it goes to 360 again in 4-5 days. My alkalinity never depletes though. I am under the impression that calcium and alk, should be consumed/dosed at similar rates. I am going to stop dosing calcium for a bit and see what happens. I might actually have calcium levels to high, and it reading low due to precipitation.
How is the alk?
