Kalk Stirrer

The motor driven design of our stirrer 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.    Technical Data K1 K2 Tank Rating 200 Gallons 400 Gallons Output Capacity 2.5 Gallons/day  5 Gallons/day  Fill Capacity* *We recommend using the Avast Marine Original Recipe Kalk.
