Cloudy water may be caused by poor filtration, low sanitizer residual, build-up of undesirable compounds or poor water balance.
To improve filtration Instant Filter Cleaner should be used to remove oil, grease and other debris from spa filters. Spa Clarifier will clear cloudy water by helping the filter collect floating particles.
Check the sanitizer residual frequently and if low use Stabilised Chlorine Granules. Spa Essentials Non Chlorine Shock will remove unwanted compounds from the water and restores water sparkle. Hight total alkalinity, pH and or calcium hardness can also cause cloudy water.
