What should you do if your saltwater pool is cloudy even though the display shows you have the correct levels and will algaecide work even though it is relatively free of algae?

Answer 1

Cloudy water really does not care what kind of sanitizer you use be it a salt system or tablet or whatever. The cloudy water is either a water chemistry problem or a filtration problem. Filtration and chemistry have to work together in order to clear the pool if one is not working properly then the pool will not clear. First take your pool water to a swimming pool store for a complete analysis including phosphates. Then balance and treat the water as they indicate. If that does not clear the pool inspect the filter system. If you have a DE filter you want to check the grids or fingers for holes and make sure all "O" rings in the filter are in good condition. If the filter has a multiport valve make sure it is in good order. If it is a sand filter and the sand is older than 5 years replace the sand in the filter. Also make sure the multiport valve is in good order and all the gaskets are in good condition. If this does not clear the pool have the TDS (total dissolved solids) checked. High TDS can cause cloudy water. You can also try flocking the pool but use this as a last resort.
