The IceCap Kalk Mixing Reactor (Small) doses kalkwasser safely and consistently, using gravity draining instead of the pressurized designs prone to clogs and leaks. An adjustable-speed motor mixes calcium hydroxide into a super-saturated, high-pH slurry that supplements calcium and alkalinity while helping stabilize tank pH. Best for: smaller reef systems or those dosing kalkwasser in smaller daily volumes Drain: gravity-fed via 1/4in flexible RO tubing into a high-flow sump area Requires (sold separately): a feed pump (peristaltic recommended for accuracy and anti-siphon protection), a timer or controller to run the mixer motor several times daily, and kalkwasser powder Maintenance: replenish the kalkwasser solution every two weeks; rinse the reactor monthly to clear precipitate buildup. The push-connect fitting and easy-access lid make both quick. Important: the mixer motor is not rated for continuous operation — always run it on a timer, never continuously. Compatible replacement parts: mixer motors and lids for the Small Kalk Reactor.
