Avast Marine Kalkwasser Stirrer

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. 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.
