the reactor. This results in a local drop of the pH-value and simultaneously to the dissolving of
calciumbicarbonate.
To avoid an overdosage, the addition of CO
method does not change the pH-value of the aquarium water.
Chemical reaction:
CaCO + CO H O -----> Ca(HCO
3 2 + 2
Calciumcarbonate + Carbonic acid + Water ------> Calciumbicarbonate
Calciumbicarbonate is easily soluble. It can be directly taken in by animals and plants and integrated into their
skeletons. By doing this, calciumbicarbonate is changed back to calciumcarbonate. During this back reaction,
CO is released which is used by Zooxanthellae for photosynthesis.

3. Working principle
The Calciumreactor KR Blue is supplied with water from the top. The flow rate should be adjusted that way
that the ph-value doesn't exceed 8.3 during the day and doesn't drop below 7.8 at night. The flow rate can be
adjusted exactly by a dosing pump (not included) and a timer (not included). If the Calciumreactor is to be
connected in a bypass, the adjustment of the flow rate has to be done manually. In this case, the flow cannot
be changed automatically during the day.
The circulation pump placed in the lid of the reactor circulates the water internally. The CO
injection port on top of the reactor. The pump sucks on CO
impeller, the CO will be nearly completely dissolved in the water. Then the CO

the Hydrocarbonate and finally circulated. Thereby, calciumbicarbonate is extracted from the Hydrocarbonate.
This is exactly the combination which corals need for their growth. The CO
Calciumreactor ensures that carbon dioxide not dissolved is pumped round the reactor several times.
The outflow is located at the top of the filter lid. From there, the water flows back into the aquarium or filter
tank. The carbon dioxide can be added from a pressure bottle.
4. Set-up
This version of the Calciumreactor KR Blue is a closed system that can also be run without a sump based
filter. The system is pressure-resistant up to 0.2 bar (2 metre water head height). Operation in the base of a
cabinet is thus safely possible. The reactor can be installed below the aquarium from where the water can flow
into a filter chamber or back into the aquarium.
Important: Never close the in and outlet of the filter completely since overpressure will arise from
carbon dioxide supply!
The inflowing water quantity has to be adjusted by using the dosing pump and timer or in the bypass operation
in a way that approx. 1 – 3 l/h flow through the 6 mm pipe into the reactor. The adjustment and the quantity
of CO depends on the aquarium size and the calcium requirements of the animals.

5. Starting
The Calciumreactor is closed with three clamps (16). Before filling, it has to be checked that the sealing (7)
is perfectly inserted and all clamps are firmly fixed. The baskets (2) for holding the hydrocarbonate have to be
inserted correctly. The thorn which is placed at the bottom of the basket has to be put in the pipe of the lowest
basket. Opposite the pipe, there is a groove into which a guide rail attached to the inner side of the container
clutches. The lowest basket may not tilt, otherwise the reactor cannot be closed. The two other baskets are put
on in such a way that the pipes are on top of each other. Each pipe has got a sealing (5) on top. Also, these
baskets have got a groove and must not tilt. The sequence of the baskets is not important. After having inserted
the baskets, the handles (3) have to be pressed into the hydrocarbonate completely. Only the upper bracket
rests level so the other handles can be taken out of the media, if necessary.
Make sure that the upper basket with the round grid (4) is closed and the reducing nozzle (9) is fixed at the
suction side of the pump. Furthermore, the 6-mm-connecting hose (15) has to be attached as connection
between the air space in the lid and the pump. Otherwise, the CO2-recirculation would not work. The lid has to
be put on the way that the pump outlet is situated above the pipes of the baskets. Laterally at the lid, there is
a pin that has to clutch into an appropriate uptake of the container.
