DIY kalk stirrer

[carmexx]

I have a few questions on the operation of the kalk stirrer.
Currently i gravity feed my sump with topoff working with a float valve.

I am curious if this setup will work effectively...
I want to Gravity feed the kalk stirrer into the bottom with rodi, up through the slurry and use a dosing pump to draw from the top of the cylinder to the sump.
I have to figure out how much i evaporate to get it right. I am getting a Reefkeeper dosing pump tomorrow. It is rated for as low as 15 ml a sec.

Will this be effective?? Is there a better way?
My diy reactor is a 2.5 qt "clickClack" pantry cylinder from the container store.
I will be ordering a small motor for the top to stir the slurry. I've seen a few on ebay rated at 60 rpm's...110v. Maybe someone out there has a suggestion on a motor?

I have been trying to build one myself b/c of certain specs that off of the shelf kalk stirrers don't have.
Below is the link for the low rpm motors that amazon sells. I am sure you will be able to find one for your setup.

Thank you for the link. I was looking at those. The other day I went to Microcenter Computer/electronics store and they had DC stepper motors in stock. They were the exact size and all , bought one, and realized i'd need a driver board for it. I am at a standstill right now. I think AC is the way to go but I'd like to hear it from the experts. I'm trying to keep this low budget.

This place always has some cheap low rpm dc gear motors,etc..

60 rpm would be much too fast. 6 rpm is better. Little AC motor will do the trick.

Avast Marine sells the replacement motor for their kalk stirrer. It's a 10 rpm 110V motor and only costs $25. Just another option.
