The Deltec KM 500 "Kalkwasser" Stirrer are ideal in supplying the marine aquarium with saturated "Kalkwasser". When connecting the "Kalkwasser" Stirrer to an automatic water level top-up system the supply of "Kalkwasser" to the aquarium is automatic.

The continiously produced acids in the marine aquaria are being neutralized, the carbonate hardness will be stabilized. An excessive increase in the pH value is being avoided through the slow and automatic (top-up system) water supply.

The Deltec KM 500 "Kalkwasser" Stirrer can be operated in combination with the Deltec Calcium Reactor with positive effect. "Kalkwasser" compensates the excess of bicarbonate of the calcium reactor through additional calcium supply. "Kalkwasser" is continiously saturated through the mixing motion.

Deltec Top-up Systems are available to supply the "Kalkwasser" Stirrer with water as and when required.

The Deltec KM "Kalkwasser" Stirrer series provide seawater aquariums with a constant supply of clear lime water (a saturated calcium hydroxide solution) and ideally complement the PF series lime reactors. The lime water compensates for the excess of bicarbonate produced by the lime reactor by supplying additional calcium. The acids continuously produced in an aquarium are neutralised and the carbonate hardness is stabilised. In addition, phosphates are precipitated by the formation of insoluble compounds. Due to the uniform and gentle addition of lime water, a sudden increase in the pH value is effectively prevented. The stirring mechanism ensures constant saturation of the lime water and the low number of revolutions prevents the direct entry of calcium hydroxide into the aquarium water. The supply of water (de-ionised water) to the lime water mixer can ideally be achieved by means of an automatic refiller.
