Key Facts

  • Includes control unit, pH electrode, calibration solutions, and mounting brackets for control unit and electrode.
  • Constant monitoring of aquarium pH.
  • Dual point pH calibration at pH 4 and 7 for improved accuracy.
  • Can be used for Freshwater CO2 System or Saltwater Calcium Reactor.
  • Automatic control of your CO2 dosing .
  • Removes the guess work out of the time your CO2 should be on.
  • Eliminates the possibility of overdosing your aquarium with CO2.
  • Suitable for 100v-240v AC.
  • Accuracy: +/- 0.01%
 

Description

Using the pH Controller you can put your CO2 deployment on auto-pilot, and only dose CO2 into your aquarium as and when it's needed.

The pH Controller constantly checks the pH of your aquarium water, so that when the pH increases, it switches on the plug, which your solenoid regulator is plugged into. That turns on the flow of CO2 which lowers the pH of the water. When the pH reaches your target level, it turns the solenoid off.

A pH Controller will also ensure that you don't 'overdose' your aquarium with CO2, either by using a timer plug an accidentally setting it on for too long, or 'end of tank dump'. It also means you only dose CO2 when it's needed, and therefore use less CO2 than you might otherwise. A pH Controller will therefore eventually pay for itself in saved CO2 refills.

Package Contents

  • pH Controller
  • Power system box
  • pH 4.0 Buffer Solution
  • pH 7.0 Buffer Solution
  • Adjustment Sticker
  • Electrode Holder
  • Instrument Holder

Instructions

  • Connect the pH electrode to pH terminal.
  • Plug your CO2 solenoid regulator (not included) or calcium reactor (not included) into the control output on the base of the unit.
  • Connect the power box to AC power (220-230V~50/60Hz) and switch on.
  • Slide switch to 'SET'.
  • Using the plastic screwdriver, adjust the "SET" knob until it reads the pH you want your aquarium to maintain. Most freshwater tropical plants like a pH of 6.5 - 6.8.
  • For use with freshwater / CO2 systems set the HI-A/LO-A switch to 'HI-A' position. For use with saltwater / calcium reactor set the HI/LO switch to 'LO-A' position.
  • Slide switch to 'PH'.
  • Put the pH electrode into the pH 7 buffer receptacle.
  • Adjust the "pH7" knob with the plastic screwdriver until the display reads “7.00".
  • Put the pH electrode into the pH 4.01 buffer receptacle.
  • Adjust the "Slope pH4" knob with the plastic screwdriver until the display reads “4.01". The device is now calibrated.
  • Put the pH electrode in the aquarium water. Ensure cap of electrode is above water surface.
  • If using 'HI-A' the controller will switch on the CO2 when the pH climbs ~0.1 above your desired pH. It will remain switched on until the pH drops ~0.1 below your desired pH.
  • If using 'LO-A' the controller will switch on the CO2 when the pH drops ~0.1 above your desired pH. It will remain switched on until the pH climbs ~0.1 above your desired pH.
  • You may wish to re-calibrate the device every couple of months to ensure accurate operation.

    I keep Discus so I need to keep the pH in a narrow range and this seems to do that and keep it very constant I keep Discus so I need to keep the pH in a narrow range and this seems to do that and keep it very constant

    Setting it up was easy and it instantly put my CO2 dosing on autopilot. It’s really precise and makes sure there's no accidental CO2 overdose. Setting it up was easy and it instantly put my CO2 dosing on autopilot. It’s really precise and makes sure there's no accidental CO2 overdose.

    I love this device. As long as you calibrate and then take steps to understand your water's degassed pH level versus your target pH level, you can't go wrong! I love this device.

    Great bit of kit and works really well. I found it's good to plug into a timer/smart plug so the whole thing switches off overnight, just to be sure no CO2 gets added while the lights are off.

    Needed something to raise the pH of soft water rather than lower and was advised by customer services to give this a go. Delivered next day, easy to set up and been working well since maintaining my pH at 5.7 For anyone interested the unit calls for small amounts of new water by activating a solinoid valve if the pH drops below 5.7, could easily also be set up to fire up a small pump.

This CO2 controller has been a fantastic addition and offers great functionality for monitoring CO2 levels and prevents any unexpected end-of-tank dump. I particularly appreciate its ability to allow me to increase the CO2 dosing slightly, resulting in the pH/CO2 level being reached, the controller switching off the solenoid and then having crystal clear water without any CO2 bubbles floating around - I'd actually forgotten what a clear aquarium looked like. I've only used it for a few days but I'm extremely satisfied with its performance.

    Very useful for monitoring CO2, preventing end of tank dump, and also enables you to crank the CO2 dosing a bit higher and then for periods of time during the day the CO2 is off and don't always have the fizzy pop look. I'm really happy with it.
