Question

Why my swimming pool water gets cloudy?

Answer 1

Your filter might not be working properly.  Have you changed the sand or cartridge within the last 5 years? If not, this could be the problem.

You could also be getting an algae problem, in which case you should look into getting some algaecide into your water as soon as possible.

Have you recently dumped in a lot of chemicals?  If so, it could be stirring up your water and making it seem cloudy.  If it is still cloudy or hasn't improved in a day or two, then it's not from the burst of chemicals.

You can try a water clarifier.  You can buy it in a liquid form (often called Clear Magic, Clear Blue, True Blue, etc) or a cube form.  It's a coagulant, meaning it bonds to the junk making your water cloudy.  After putting it on, leave your pump on for at least 8 hours.  The junk should be settling at the bottom and you can use your pool vac or automatic cleaner to vacuum it up.

You should also bring a sample of your water in an old water bottle to your local pool store, they can test it for free and tell you if there is some sort of chemical imbalance in your pool.
