4. The calcium reactor can be run 24 hours a day, but usage should be adjusted according to
levels of calcium/KH demand and depletion in the aquarium and in conjunction with regular
water testing.
5. We also advise regularly monitoring and testing the calcium and dkH levels of the water
exiting the calcium reactor. These levels will be higher than those of the water inside your
aquarium, assuming the levels in your aquarium were originally within the normal range.
USEFUL TIP: The amount of CO
water flow through the REEF-React unit will vary depending on the individual requirements
of your aquarium. This can be ascertained through regular water tests, and the dosage rate
of CO
and the water outlet flow rate should be adjusted accordingly. When using a

calcium reactor and dosing CO
This is normal, but if the pH level in your aquarium has dropped significantly please refer to
problem 1 in "Trouble-Shooting". Always ensure your magnesium level is withing the
normal range.
OPERATION WITH A pH MONITOR/CONTROLLER
REEF-React Calcium Reactors incorporate a pH probe holder so they are also ideal for
incorporating into more advanced aquarium set-ups where pH monitors/controllers are to be
used. For such applications a pH probe can be easily installed into the lid of the REEF-React by
following the simple steps highlighted below:-
1. Switch off the pump (19).
2. Close the valve (8a) on the water flow indicator (8), stopping the siphon/or your reactor
supply pump.
3. Carefully unscrew the locking nut on the pH probe holder (17)
4. Remove the watertight gasket and gasket plug from the cap assembly.
5. Remove the gasket plug from the watertight gasket.
6. Slide the pH probe holder locking nut onto the pH probe.
7. Slide the watertight gasket onto the pH probe.
8. Re-position the watertight gasket and probe into the REEF-React lid.
9. Carefully re-secure the pH probe holder locking nut.
10. Switch on the pump (19).
11. Ensure that all connections have been made correctly and that there are no leaks.
12. Restart the siphon & open the water flow indicator control valve (8a) or start your supply
pump/flow line.
USEFUL TIP: The optimum pH inside the reaction chamber should be approximately 6.5 to 6.7.
MAINTENANCE
Caution: To avoid possible electric shock, special care should be taken when using any
electrical appliance near water.
Caution: Always isolate the pump from the mains electricity before installing or carrying out any
maintenance to the calcium reactor and stop the water supply from the aquarium or sump.
1. Check regularly to ensure that the water flow through the calcium reactor is as required.
We strongly advise that this is checked daily as part of your visual daily checks.
2. REEF-React Calcium Reactors should need very little adjustment and maintenance once set
up correctly. However, it is common for deposits to build up on some of the
fittings/components and therefore it is recommended that the calcium reactor is cleaned
periodically.
3. Clean and remove any build up of calcium/salt deposits on the water intake strainer and the
water outlet control valve.
USEFUL TIP: If calcium deposits are present, soak parts in a diluted vinegar or kettle
descaling solution and then thoroughly rinse with RO water before use.
