Help with Kalkwasser and PH

[smh254]

I'm having a problem with keeping my PH up so I was thinking about adding Kalkwasser to my ATO. Right now I dose calcium alkalinity and magnesium. My question is should I stop dosing These if I start using Kalkwasser? 40b 20g sump mixed reef but more SPS than anything.

Where is your ph now?

How much of exactly what material are you dosing now? We can advise how much limewater (kalkwasser) would be equivalent to that amount of calcium and alkalinity.

PH right now is at 7.75 goes up to 8.1 in the afternoon. I dose 30ml calcium and 25ml alkalinity a day.
