| PROBLEM | PROBABLE CAUSE | REMEDY |
| Water leak | A) Compression fitting (unions) have loosened. | Tighten fitting. |
| B) Pump seals leaking. | Call for service. |
| C) Heater gaskets leaking. | Replace gaskets or call for service. |
| Cloudy water | A) Clogged or dirty filter. | Rinse off debris and clean filter with degreaser. |
| B) Insufficient sanitizer or calcium hardness. | Add sanitizer and calcium hardness. |
| C) Insufficient filtration time (does NOT apply to 24hr. circ. pump set ups). | Increase filtration to a minimum 4 hours per filter cycle (8 hours per day). |
| D) Particles too small for filter. | Add clarifier. |
| E) High pH and / or alkalinity. | Adjust pH with pH Down. |
| F) Trace metals in water. | Use metal remover |
| G) Too much clarifier use. | Wait to be filtered out. |
| Green water | A) Algae. | Add algaecide, super chlorinate and add Shock. Check ozone generator. |
| B) Metal corrosion in equipment. | PH too low, adjust to 7.2 to 7.6 with pH Up. |
| Brown water | Iron present in water. | Super-chlorinate and add Shock. Add metal remover. |
| Bleached hair/bathing suits. Eye irritation. | Too much chlorine. | Allow to dissipate. Add Oxy Shock. |
| Bad smell, eye & skin irritation, complaints of too much chlorine. | Too many chloramines, not enough free chlorine in water. | Super-chlorinate and maintain 3 – 5 PPM. Add Shock. |
| Scale formation on walls and equipment. | A) High pH. | Reduce pH to 7.2 to 7.6. |
| B) Calcium too high. | Drain 20% to 40% of tub and refill with “soft” water. Maintain at 150 to 400 PPM. |
| pH fluctuates radically | Total alkalinity out of balance. | Balance alkalinity. |
