I have a spectrapure ATO that I want to use for kalk because it's a perfect peristaltic pump for kalk. I don't like kalk in the ATO so I was looking to have the pump come on every hour. I tested the pump and found it doses @ 175ml a min. There is no way to adjust it. I would pump 350ml (2 minutes) every hour for 6-8 hours. Are there any issues with pumping that much kalk every hour for 2 minutes? I'm used to dosing kalk slowly and the max i've seen is the BRS 50ml a min pump.

50g and in the sump return. The return shoots near a power head so the flow is high.

That 350 mL added at once won’t raise the pH of the tank too much, so just try to get it mixed into a large volume as quickly as you can.
