To fill the reactor, 3 - 4 cups (coffee cups) of Kalkwasserpowder are dissolved in approx. 1 litre of
fresh water and will for a milky liquid. This liquid is filled into the stirrer. Now, the stirrer is filled up
to the top with fresh water. If the reactor is already full, the outlet tube has to be directed into a
bucket so surplus water is drained. Now, the stirrer with the motor can be mounted. As soon as the
upper part of the liquid in the reactor clears up – a little turbidity is normal - the refill pump can be
started again.

The water is pumped through the Kalkwasserstirrer by the dosing pump and from there to the
aquarium. The dosing pump is controlled by a level control (aquaniveau). (Dosing pump and
aquaniveau can be replaced by Niveaumat). As soon as water evaporates in the aquarium, the
dosing pump is activated and water is pumped from the reservoir via Kalkwasserstirrer into
aquarium.
5. Maintenance
The motor of the Kalkwasserstirrer has a lifetime of approx. 1 year. After that, it has to be
changed.
6. Kalkwasser and Calcium reactor
More and more of reef aquarists use the calcium reactor in combination with Kalkwasserreaktor.
The calcium reactor produces free carbon dioxide that is neutralized by Kalkwasser. Phosphates
also those that are produced by the calcium reactor are precipitated by Kalkwasser. However, you
should avoid an overdosing of calcium. Experiments have shown that overdosage of bicarbonates
and carbonates result in bleaching of red lime algae and corals do not open their polyps fully. The
carbonate hardness (alcalinity) plays only a minor role in this process. Problematic is their quick
dosage especially during daytime. The reason of this findings are not fully understood till today. In
any case, a sufficient calcium supply of reef aquariums is one of the basic requirements.
Aquaria with low levels of calcium and high carbonate hardness (alcalinity) cannot be adjusted to
the right calcium level neither with a Kalkwasserreaktor nor with a calcium reactor. To raise the
calcium content for 50 ppm, the carbonate hardness has to be raised by 7° KH (2.5 mmol
alcalinity). In this case, the only possibility is to add calcium chloride, e. g. REEF LIFE Calcium
until the desired value is reached. This value is then kept constant with the Kalkwasserreaktor and
calcium reactor.
