View Full Version : Kalk reactor, how often do you mix your kalk?

Hi there. Just putting a kalk reactor online. The kalk reactor is driven by a Litermeter and I will be dosing about 1 liter of kalk/day. My reactor uses a powerhead to stir the kalk. I was thinking maybe 1x/day to mix the kalk should be sufficient. Curious to see what everybody else is doing.

4 x's/day for 3-minutes each.

Be prepared to replace impellers if you're using a MJ to mix. I used to run a DIY one with a MJ-600 for mixing and had to replace impellers about once every 3 months; it ran 4x a day for 1min.

I switched to an Aquamedic with a top mounted motor and stir bar, and it mixes 24x7.

I've had my MJ600 going strong for almost a year before I had to change the impeller only. Not a big deal at $7/replacement imho.

mine is going over a year also..

one thing worth noting once the solution is saturated mixing more doesnt help..i actually red its not good to over stir...

so if you mix a few times a day for like 30 seconds that should be fine..the upper clear solution is still saturated unless you have used that much top off
