| Problem | Possible Cause | Check / Remedy |
| Green water/cloudy water |
Inadequate sanitiser levels. Algae may be present |
Shock dose the water with Spa Fusion or use a double dose of Spa Stabilised Chlorine Granules or Spa Bromine Granules or consider if time to drain/re-fill |
| Too much chlorine |
Overdose |
Allow time to naturally dissipate or purchase a chlorine reducer |
| pH level hard to control |
Total Alkalinity low |
Apply Spa TA Plus to raise total alkalinity level |
| Cannot maintain chlorine levels |
Chlorine demand of water too high at start up, after holidays or due to excess contamination or neglect |
Shock dose the spa water with Spa Fusion or use a double dose of Spa Chlorine Granules or Spa Bromine Granules. Repeat after 24 hours if necessary. |
| Foaming water |
Oils/detergents present |
Use Spa FoamAway |
| Cloudy water |
Poor chemical control or inadequate filtration |
Clean filter cartridges or consider if time to drain and refill. Retest water and add chemicals if necessary. |
| Rough spa surfaces |
Scale formation |
Ensure pH and total alkalinity levels are correct and if necessary use Spa ScaleAway to stop scale build up. |
| No colour change on test strip colour pads |
High chlorine levels may be bleaching indicator pads (over 15 ppm chlorine) |
Check expiry date on test strips. Wait for chlorine level to drop and re-test |
| Test results vary |
Air bubbles can increase pH temporarily and reduce total alkalinity over time |
Test when circulation pump running (not jets) for true results. |
