Kalk Stirrer Kit

$ 169.99

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.

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.

Assemble Yourself Kalk Stirrer

Easy to put together watching the video. Does what it's supposed to do without issue. Use a check valve with it. First time I used it kalk slurry siphoned back into my ATO container.

The DIY I Was Looking For

I love how this is a kind of hybrid DIY project. The research and development which takes the most time and money is done, and I get to do the assembly, which is something I like doing. This is a cool option Avast Marine offers for some of there products and sets them apart from other product lines. Great responsive customer support as well.

Great stirrer, fun kit

I was glad to save some money on the kit and actually had fun putting it together. It was a really easy process and now I have it running being fed by a dosing pump. Kh and pH have been beautifully stable since getting it up and no messing with two part for the moment. Really pleased with it.
