3. If after 24 hours the pH of the water exiting the V
2
React is the same as that of your aquarium then
carefully increase the amount of CO
2
bubbles injected into the CO
2
bubble counter to
approximately 30 bubbles per minute (1 bubble every 2 seconds).
please note:
The adjusted CO
2
bubble dosage should only be maintained until the desired pH level is
achieved and care should be taken to avoid excessive CO
2
in the aquarium.
USEFULTIP:
after carrying out any changes to Co
2
dose rates or water outlet
flow rates allow at least 24 hours before re-testing water parameters.
4. The calcium reactor can be run 24 hours a day, but usage should be adjusted according to levels of
calcium 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 should be slightly 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
2
that you dose into the V
2
React and the required water flow
through the V
2
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
2
and the water outlet
flow rate should be adjusted accordingly. When using a calcium reactor and dosing CO
2
the pH
level in your aquarium may be lower than usual. This is normal, but if the pH level in your aquarium
has dropped significantly please refer to “Problem: pH level in aquarium is low” in “Trouble
Shooting” below.
EXCEss Co
2
If your aquarium has a high calcium demand and you have adjusted the CO
2
supply to allow for this
you may encounter a slight build up of excess CO
2
within the reaction chamber (13) of the V
2
React.
This is easily identified by a drop in the water level within the reaction chamber. This can easily be
rectified by un-screwing and temporarily removing the lid (1) which will allow the excess CO
2
to be
released and the water level within the reaction chamber to be corrected. If this regularly occurs,
we advise that you slightly reduce the amount of CO
2
being dosed.

The V
2
React Calcium Reactor can be incorporated into more advanced aquarium set-ups where pH
monitors/controllers are to be used by replacing the standard lid (1) supplied with the unit with the
V
2
React 300 Compact modified probe holder lid (sold separately part no.5784). In doing so, a pH probe
can then be easily installed into the main body of the V
2
React by following the simple steps below:-
1.
Switch off the pump (14)
2.
Remove the water supply intake strainer (6) from the aquarium or sump.
3.
Replace the standard lid (1) with the V
2
React 300 Compact modified probe holder lid.
4.
Carefully unscrew the pH probe holder locking nut (see diagram A below).
5.
Remove the watertight gasket and gasket plug from the cap assembly.
6.
Remove the gasket plug from the watertight gasket.
7.
Slide the pH probe holder locking nut onto the pH probe (see diagram B below).
8.
Slide the watertight gasket onto the pH probe.
9.
Re-position the watertight gasket and probe into the V
2
React 300 Compact modified probe holder
lid.
10. Carefully re-secure the pH probe holder locking nut.
11. Re-connect and re-attach the water intake strainer (6).
12. Switch on the pump (14).
13. Ensure that all connections have been made correctly and that there are no leaks.
USEFUL TIP:
The optimum pH inside the reaction chamber should be approximately 6.5.
