View Full Version : Kalk stirrer with pH controller

07/08/2012, 11:53 PM
Just bought a avast marine works K2 kalk stirrer to rasie the pH that my calcium reactor is making low. Can you use a pH controller to dose kalk from the stirrer when pH drop low. Or will this have negative side affects on my 250 gallon aquarium?

I just add Kalkwasser to my ATO resivor. Keeps the PH between 8.0 and 8.2. If you dose Kalkwasser based on PH your salinity might be thrown off. A better solution would be a co2 scubber. I will get one for the upcomming winter.
