Reactor dosing kalk from topoff

[roggy23]

So I have a reactor kalk stirrer.. The tunze autotopoff pumps water into reactor then the kalk gets gravity fed into sump.. it’s not raising my ph to the levels I want. It’s about 8.15.. I think the evaporation is not fast enough to dose the amounts tank needed to get to 8.3… does this mean I should use a doser instead and if so how do I figure out how much to dose and how often to get to 8.3?

You should determine kalk dose based on tank alkalinity, not pH. In terms of pH you get what you get.

Are you measuring alk?

Ya I’m at 8.5
