Troubleshooting
26.1 KH readings fluctuating
This is the most reported symptom, and it almost always has one of these causes. Work through them in order:
| # | Check | Action |
|---|---|---|
| 1 | Aeration in both chambers | Set the side valves for strong, equivalent airflow, with at least 5 mm of foam. If the air pump is weak, clean the air system or replace the pump |
| 2 | Probe age and health | Over 12 months in use, or Health below 55%, replace the probe |
| 3 | Chamber cleanliness | Empty, open the lid, clean, refill and recalibrate |
| 4 | Aquarium chemistry | Borate, phosphate, silicate or organic matter above normal affect the measurement |
| 5 | Stray voltage in the water | Check for current leaking from aquarium equipment |
| 6 | Lanthanum in use | Suspend measurements during treatment and for 6 to 12 hours afterwards |
| 7 | Hose position | Move it away from detritus, the skimmer and the dosing point |
| 8 | Still fluctuating | Contact support: we can assess the reading circuit's statistics remotely |
26.2 Other symptoms
| Symptom | Solution |
|---|---|
| Software updates do not complete | Format or replace the memory card |
| Graphs do not appear | Format or replace the memory card |
| System Status shows SD: Not Detected | Format or replace the memory card |
| Noise during aeration | Check the air pump's mounting — use silicone glue or double-sided tape |
| Noise from the dosing pumps | Clean or replace the internal tubing |
| Traces of water in a dosing pump | Replace that pump's internal tubing immediately |
| Internal reservoir level low | Usually a consequence of power cuts during measurements. Empty completely, refill and recalibrate. If it persists, a level sensor may have a sealing fault — contact support |
| Equipment restarting on its own | Check the power supply and the memory card |
| Trouble reaching it through the cloud or app | Check Wi-Fi signal quality and internet access under System → System Status → Network |
| Dosed volume rising, with another replenishment system | Not a fault: your main system is not keeping up, and the doser is making up the shortfall. Check the reservoir, the reactor's CO2 and media, the tubing and the pumps, or increase its dosage (Chapter 16) |
| Doser on, but not dosing | Check whether the home screen shows Calibrate (calibrate the pump), whether the mL to raise 1.0 dKH field is filled in, whether the bottle has product, and whether measurements are taking place (Chapter 16) |
| CO2 Port always at 100% and KH falling | The reactor is not delivering: CO2 empty, media exhausted, valve blocked or too few bubbles (Chapter 17) |
| CO2 Port on in the app, but the solenoid or the pump does not run | The port does not supply power. Check that the input cable (IN and N) is plugged into the wall outlet or the power supply, and that the load is rated for the same voltage (Chapter 17) |
| Circuit breaker trips when the CO2 Port switches on | The power cable has one wire in IN and the other in OUT. Unplug it and move both wires to the bottom pair, IN and N (Chapter 17) |
