Kalk Stirrer Kit

$ 159.99

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.

K1 Ultimate Kalk stirrer

I love this unit. DIY was easy and nice complete kit. I had to run a bead of glue around the body connector because it dripped, no big deal. I had another kalk reactor for a larger system but it wouldn't fit under the stand on my 100g. Looking forward to not needing to replace mixing pumps due to broken impellers. I will be adding more Avast products to my system.

Simple to assemble and works great

The DIY kit was simple to assemble. The video does a great job. As far as operation effectiveness, it keeps the solution saturated 24/7. Works great!

Great Kalk Stirrer

Great quality materials. The assembly video is easy to follow and the unit was fun to put together. Will definitely buy from Avast again.

Diy needs work

Instructions... where are they? Also I see the package includes sandpaper which I assume it’s for you to make the parts fit because it was a challenge to make everything fit. Also the stirrer is not straight so not too happy with how it turns.
