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.

I'm a new ******

Product was pretty easy to assemble with the YouTube video. I have it running on a 46 Bowfront Softie and LPS tank in line with my ATO. I've only had it running for a few weeks but it works as advertised. No issues with purchase or shipping

Great Kalk Stirrer- easy and fun build

Purchased the K1 Kalk Stirrer and it arrived quickly and unscathed. Everything you need to put this together comes in the box and if you watch the youtube video for it you can install it without a hitch. Works prefectly! Very pleased with quality and function and so much easier than mixing kalk in your ATO!

Great Product

I am very pleased with the performance of this product. I bought a 5.5 inch unit last year and decided to go with the larger size on my main system. It works very well and was simple to assemble.
