    The world famous GEO kalkwasser reactor!

    Our kalk reactors are fabricated using only the finest cast acrylic materials and high quality fittings.
    Designed with the user in mind, we feel these are by far the easiest reactors on the market to install, operate and maintain. Easy fill fitting on the lid for adding kalkwasser as needed. You only need to remove the lid for cleaning the reactor.

    Drain valve allows you to lower water level in the reactor when adding fresh kalkwasser. You simply remove water from the reactor into a container of kalkwasser, stir it into slurry and pour it back into the reactor through the easy fill opening.

    The dependable Maxi Jet stir pump mixes the powder in the chamber; there is no chance of powder exiting the reactor, even if the dosing is pumping water through the reactor as the pump is mixing.

    1. I love this thing Review by Zorron

      This is a quality piece of equipment. I should have bought this a long time ago. This item keeps my top off water good and saturated with KALK. Very simple set up and easy to maintain. (Posted on 3/7/2009)

    2. This product is the best Review by tmcarter

      This product is the best Ive used. Simple, easy to set-up. Low maintenance. Needs a timer to control the external powerhead that mixes the powder. The concept is so much superior to the internal mixers/stirrers. No internal moving parts. Only the external powerhead that directs turbulent flow to mix the powder. High-quality, state-of-the-art workmanship and materials.
      Best of the best. (Posted on 12/30/2008)
