|Problem ||Possible Cause ||Check / Remedy
|Green / cloudy water / slippery sides
||Shock dose with chlorine (see start up dose) and add algaecide.
|Too much chlorine
||Allow time to naturally dissipate or buy a chlorine reducer.
|pH hard to control
||Seek advice on how to raise total alkalinity.
|Can’t maintain chlorine levels
||Chlorine demand of water too high at start up, after holidays or due to excess contamination or neglect
||Shock dose with chlorine (see start up dose) and repeat after 24 hours if necessary.
||Poor chemical control or inadequate filtration
||Clean cartridge, check chemical levels and adjust chlorine / pH if necessary. If problem persists buy a pool clarifier to remove small particles.
|Rough pool sides / Pool liner feels rough
||Scale formation due to high calcium levels in water
||Ensure pH levels are correct and use a pool scale inhibitor to stop calcium precipitating out of water.
|No colour change on test strip / dip test
||Levels of chlorine too high leading to bleaching of indicator pads (over 15ppm chlorine)
||Wait for chlorine level to drop and re-test.
||Detergent present from incorrect cleaning products or excessive algaecide use
||Reduce water level and top up with fresh water. Avoid domestic household cleaners.
