Will this even work ?

I'm currently mixing a gallon of kalk every few days and swapping jars. I want an avast marine kalk stirer but I do not want to pay $240. I'm not super interested in buying a low rpm motor off Amazon because it's just another thing to maintain / worry about heat sink.

I found this image online, I'd like to try to clean up the concept but is this even feasible if run off a doser that averages 42 mil a minute ?

ok, I get the concept might work but there is a major problem: refilling. I don’t know about anyone else but I tend to get water dripping out of those canisters each time I swap the filters on my RODI. Having lime water get all over sounds like a good way to get chemical burns. No thanks.

I'd use a different canister. And probably drill a bulkhead that would feed into the sump via gravity. I'm more confused on if a low rpm doser fed to the bottom would even "mix" it
