The new motor driven design of our stirrer silently and gently mixes your calcium hydroxide 24 hours a day. This ensures that you are always dosing the freshest possible kalkwasser to your system. Since the undissolved particles are always kept at the bottom and the clear liquid is always at the top, this is the safest available way to dose kalkwasser. The simple top loading design reduces the amount of time spent adding kalk powder to the reactor, which can be refilled in less than 1 minute.

No more powerheads to clean or replace, no more large vats of lime water taking up valuable space next to your tank. Once you try our stirrer you'll never look at kalkwasser the same again.

Note that our stirrers are non-pressurized chambers; water enters through a 1/4" John Guest fitting in the lid and gravity drains out into your sump through the 1/2" union barb fitting in the side. The lid is not fixed in place; it lifts off for quick and easy kalk powder refills.

If you plan to install a kalk stirrer in your auto top-off system, we recommend this small valve to control the output of the pump to a fast drip.  If you have a Tunze ATO, use this fitting to connect their tubing to the pushlock connector on the lid of the stirrer.  Please see the kalk stirrer manual for additional installation tips and ideas.

Amazing Kalk Stirrer

I was using a DIY kalk stirrer I made from media reactor I had. The Avast Kalk Stirrer blew my DIY unit away. If you are on the fence, just get it, you won't be disappointed.

Kalk stirrer

Though I have not used this unit yet ( tank still too new to need ) from all the research this one checked all the boxes . Able to run in or out of sump , not pressurized. Motor on constant which makes setting up to a controller easy with a PH probe port built in . Outlets fits over sump walls . What’s not to like
