You will see that on the controller there is a central LCD display and a number of LED indicators and buttons
as shown on the diagram below.
A – Mode button
B – Water flow rate per 24 hours in litres*
C – Degassing after ‘X’ litres*
D – Recirculation pump speed %*
E – Process active/complete %
F – Increase button for items marked *
G – Decrease button for items marked*
H – Activity indicator - green/yellow/red LED
J – CO2 valve open/active – blue LED
K – CO2 Bottle empty (audible alarm) – RED LED
L – Degassing cycle running
A – Mode button
: Press and release this button to scroll through the various function displays on the central
display. Continued pressing scrolls through these 3 functions in a loop.
> Press – displays reactor output water flow volume per 24 hours in litres. LED B illuminated.
> Press – displays water flow volume between degassing cycles. LED C illuminated.
> Press – displays reactor recirculation speed 0-100%. LED D illuminated.
To adjust the value of functions, press button F to increase and button G to decrease.
Mode flow function
- Pressing the mode button for 4-5 seconds when in daily output mode will cause the
supply pump to run for a cycle 0-100 and then stop. Press again to reactivate for another cycle.
This is particularly useful for adding small amounts of water to the reactor during the final filling stage.
B – Water Flow:
The LED display gives a readout of the total water/effluent that passes through the reactor
in a 24-hour period, (assumes that the optional timer function is not used), and can be increased and
decreased in 1 litre steps from a recommended minimum of 10 litres/day to a maximum of 350 litres/ day
The smart controller calculates and splits the total daily litres required into smaller volumes which are dosed
automatically in approximately 5-minute intervals throughout the day using the flow meter.
It is therefore possible to calculate the total dKH required per day and to adjust the levels in the tank by
simply increasing or decreasing the total volume of effluent dosed by the reactor.
C – “Degassing After” volume:
As the media melts in the reactor, air and inert gases that were trapped in the
substrate are released. These gases dilute the pure CO2 and reduce the ability of the reactor to maintain a
lower pH which gradually rises throughout the day. This can be seen on the pH graph below.
A degassing cycle flushes out all of the gas in the reactor chamber and replaces it with fresh CO2 to maintain
the optimum low pH and therefore the maximum output from the reactor.
In general, we suggest degassing only once a day however the chart above is illustrates the pH changes for
an aquarium that is being degassed 3 times per day.
