NaOH Dosing

Rwade · Dec 20, 2022

Can NaOH be used in a magnetic stirrer as I do with Kalkwasser? I currently dose Kalk with a stirrer but my Calcium is high, so I’m would like to dose Alk and get increased PH without dosing Calcium. My mag stirrer has a RO input through a dosing pump and gravity flows into my sump, I add Kalk as needed to maintain a saturated solution. Does NaOH reach saturation, with excess solids in the bottom to be mixed into solution as needed? And if this is feasible, would the dosage be the same to get the same Alk boost?

It is incredibly soluble, so cannot work in this fashion.

Bummer, now I have to reroute my lines and calculate dosage. What’s the dosage for a .25 Alk dosage in 175g water volume.
