LF Avast Marine Kalkstirrer STL File

Anyone have a file for a propeller for the stirrer to increase stirring up the shaft

That would be interesting to see as the current one does almost nothing and have taken my unit offline . Would the stock motor be fast and strong enough?

My Kalkwasser stirrer works awesome.

I’ll probably just design one but figured I’d ask before I start tinkering lol. I’ll keep you posted for sure. Yes the motor can be replaced and I’ve read that a 45rpm motor seems to be the best, but need more disturbance from the shaft it’s self to actually get some results and get the entire chamber milky.

You actually don't want the entire chamber murky. only the bottom. If you remix kalkwasser too much it looses potency for your corals.
You also don't want to 'puck' the kalk in the bottom of the container by not mixing it enough.
mixing along the entire shaft is no recommended provided the source water is feed in at the bottom.

I use 6" PVC translucent tubing because I've found having a wide mixing chamber allows the top to remain relatively undisturbed while still mixing the bottom. The fully saturated kalkwasser at the top eventually overflows into the sump as new RODI water is dosed from the bottom and is mixed. The mixing schedule is carefully tuned for 2 cups of Kalkwasser powder at a time so you could conceivably go months without having to think about it.
