When it comes to cloudy pool water, the issue may be caused by one of two things:
a) The pool water chemistry is imbalanced.
b) The filter isn’t functioning properly.
When it comes to your pool water and its chemistry, it’s likely due to a high pH or too much stabilized chlorine in the water. Either lower the pH by using dry acid until optimal chemistry is obtained, or replace some stabilizer with water to increase it.
In regards to the filter, start off by backwashing it (if any parts require repair or replacement, do so). Increase your free chlorine levels to 10 PPM and then polish your water off with a clarifier.
