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. Simple top load 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 new line of stirrers 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.

Had fun building the kit, which was well packaged and easy to do. So far, the unit has been working great. Very happy with my purchase.

Love that I could assemble it myself

Assembled easily and saved a fair bit of money. Assembly video made it really easy. Stirrer is working fine!

easy enough to DIY

It was easy enough to DIY with the online tutorial etc. couple of things to consider: 1. if you use the applicator to spread acrylic glue its a one use deal, I used it and set it down for a couple of minutes and it was sealed. I was able to use glue without applicator easy enough. 2. the stirring rod was somewhat bent a little, this caused the stirrer to hit against chamber wall, had to heat it up somewhat and bend in opposite direction to prevent rubbing wall. Still a little wobble but it will suffice until I replace with stainless steel rod. 3. acrylic chamber was not cut exactly straight had to sand the heck out of it to get it to seat and allow gluing without being crocked. 4. does what its advertised to do but if you're not handy with tolls etc. pay the extra money and get one already constructed.
