Use our KW Reactor with any small powerhead of about 200 gph, or with high pressure top-off pumps. A tiny rotating sprinkler pushes about 5 gph of the top-off water upward through the calcium hydroxide, automatically mixing it to achieve a supersaturated kalkwasser solution. A programmable timer is needed to limit the on times. Can be used with calcium hydroxide or sodium hydroxide and connected to a pH controller for automatic pH maintenance. Very convenient design that can be mounted hanging on the back of the aquarium or below the aquarium. Includes check valve and flexible connection fittings that rotate 180 degrees to allow a perfect custom fit to your installation. Threaded lid design makes adding calcium hydroxide or servicing quick and easy. For aquariums up to 300 gallons. Patented design by Julian Sprung.
