Filling the reactor:
Before refilling the reactor, remove the plug from reactor and the refill pump from the mains. Open the bayonet
(turn left). Take care not to lose the O-ring. Undissolved residues of the Kalkwasserpowder should be removed.
Clean the reactor.
To fill the reactor, 2 cups (coffee cups) of Kalkwasserpowder are dissolved in approx. 1 litre of fresh water and
mixed for a milky liquid. This liquid is filled into the stirrer. Now, the stirrer is filled up to the top with freshwater.
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.

3. Aquaniveau
The water is pumped by the dosing pump through the Kalkwasserstirrer 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 the 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 the Kalkwasserreaktor. The Calcium
reactor produces free carbon dioxide that is neutralized by the Kalkwasser. Phosphates, also those that are
produced by the Calcium reactor are precipitated by the Kalkwasser. However, you should avoid an overdosing of
the calcium. Experiments have shown that overdosage of bicarbonates and carbonates results in bleaching of red
lime algae and corals do not fully open their polyps. 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 up 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 had to be raised by 7°KH (2.5 mmol alcalinity). In this case, the only possibility is the addition
of calcium chloride, e.g. Reef Life Calcium until the desired value is reached. This value is then kept constant with
the Kalkwasserreaktor and the Calcium reactor.
