CHAPTER 25
Maintenance routine
The Aquarino KH asks little, but it asks regularly. This routine keeps measurements trustworthy over the years.
| Frequency | What to do |
|---|---|
| Weekly | Look at the last 24 hours in the graph · check the aeration foam in both chambers · check the buffer reservoir level |
| Monthly | Run a chemical test and compare with the equipment · partial calibration if needed · inspect the chambers visually |
| Quarterly | Clean the chambers internally, then run a full calibration · check the doser tubing |
| Yearly | Replace the pH probe and log the replacement · replace the doser's internal tubing |
25.1 Cleaning the chambers
- Empty the reservoirs completely under Configuration → Reservoirs → Empty.
- Open the lid and clean the inside of the chambers.
- Close it, run Fill and perform a full calibration (Chapter 10).
There is a video of the procedure at https://youtube.com/shorts/qm--dZ7LNUg
25.2 Memory card
The card holds the history, the event log and the interface files. When it fails, the symptoms are characteristic: graphs stop appearing, updates do not complete, or System Status shows SD: Not Detected.
The fix is to format or replace the card. Talk to support first — in many cases we can identify the cause remotely.
25.3 pH probe
- Rinse only with drinking water — never with reverse-osmosis, distilled or deionised water, which attack the bulb. Never wipe the bulb with cloth or paper.
- Never let the probe dry out — more than 30 minutes in the air can damage it permanently.
- Replace it every 12 months, or sooner if Probe Health falls below 55%.
- Always log the change under Configuration → pH Probe → Log probe replacement.
