Cloudy water is a common problem in spa pools and swim spas. Your water needs to be tested regularly to find the cause so you can treat the issue.
Please be aware that a combination of the below issues may be contributing to cloudiness and water that doesn't appear crystal clear.
Most common causes of cloudy spa water and solutions:
Unbalanced water - Test water and adjust using the appropriate chemicals
Not enough Sanitiser - Use Spa Shock to increase to the correct level. If you are using BioGuard Armour, then use the Oxidiser dosage.
Unusual use – eg. visiting family or excessive bather load - Shock treat, clean filters, use Spa Clarifier
Filter cartridges (not clean)- Clean filter cartridges with filter cartridge cleaner and rinse thoroughly
Filtration set up – Check suction, step up filtering to 4 hours/per day
TDS (Total Dissolved Solids) levels - Dump and refill after using Pipe Degreaser
Overdosing with calcium hardness - Empty 1/3 of water and refill
Not enough calcium in water – Add calcium increaser
Pollutants from around the spa – eg: building, plant overhang etc - Use Spa World clarifier
Smelly when cover removed – Clean underside of cover with Pipe Degreaser, rinse and dry in sun.
NOTE: Please also check the following:
For hard water – lower pH to 7 and Alkalinity to 80 ppm.
For tank water – check calcium and phosphate levels.
