SYMPTOM | PROBABLE CAUSE | SOLUTIONS |
Algae | High pH | Shock with “POTASSIUM PEROXY |
|
| MONOSULFATE”; adjust pH. |
| Low free chlorine/bromine | Shock with “POTASSIUM PEROXY |
|
| MONOSULFATE”; maintain sanitizer at |
|
| recommended level |
Eye Irritation | Low pH | Raise pH with |
| Insufficient free available | Shock with “POTASSIUM PEROXY |
| chlorine/bromine | MONOSULFATE”. |
Skin Irritation/Rash | Unsanitary/polluted water | Maintain recommended sanitizer residual at |
|
| all times; |
| Chlorine/bromine level too high | Allow chlorine/bromine level to drop below |
| (above 5ppm FAC) | 5 ppm before using spa. |
Stains | pH or total alkalinity too low | Adjust pH and total alkalinity; use |
|
| sequestering agent; drain and clean with |
|
| appropriate product. |
| High iron or copper in water source | Use sequestering agent for metals; |
|
| adjust water |
Scale | Too much calcium dissolved | Adjust total alkalinity and pH levels by |
| in | adding the appropriate sodium bisulfate |
|
| product; with concentrated scale deposits, |
|
| drain the spa, clean the liner as outlined in |
