| Can't maintain chlorine levels |
Unsatisfied chlorine demand in the water at start up, after holidays or due to excess contamination or neglect |
Shock dose pool with liquid shock or granules and retest after 24-hours. If chlorine level is still low repeat shock treatment |
| Too much chlorine |
Too much chlorine was added to pool |
This is only a real problem if the chlorine is over 10mg/l (ppm). The chlorine level will naturally dissipate in time or can be reduced by chlorine reducer |
| pH hard to control |
pH levels can be difficult to control if the total alkalinity is incorrect |
Seek advice on the products and method to correct total alkalinity level |
| Green water |
Usually caused by an infestation of algae |
Shock dose pool with chlorine and add algaecide |
| Cloudy water |
Usually occurs after poor chemical control or inadequate filtration |
Clean filter, check and if necessary adjust chemical levels (chlorine & pH). If problem persists use water clarifier to assist filter in removing small particles |
| Scale Formation |
This can happen in hard water areas due to high level of calcium in the water |
Ensure the correct pH level is being maintained and use a scale inhibitor to prevent calcium precipitating out of the water |
| No colour change on Test Strip pads after being dipped into pool water |
If chlorine level is over 15mg/l (ppm) the colour on the pads can be 'bleached' out |
Check expiry date on Test Strips. Wait for chlorine level to drop and retest | |
