Symptom Reason Cure 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
