Pool filters only filter out leaves, bugs, and other foreign objects that somehow get in the water.If they had a working filter on the pool it would not get cloudy from people not rinsing. Learn a few things about how you take care of a pool.
This is dumbest thing I have heard.
Their filter membrane is not fine enough to filter out body grease or hair produces.
Do you understand how a pool works? Do you understand how a pool filter and chlorine works?
The people who ran these pools either didn't check their chemical levels, and or didn't put in enough chlorine. The pool was probably cloudy from the warm weather and poor chemical control.
Ohhhh, YOUR definition of cloudy PROBABLY because of warm weather and poor chemical control is CLEARLY more believable than the people who were actually dealing with the matter and do not preface their conclusions with "probably".
