Green and Cloudy Pool Even After Pool Shocking

Have you ever experienced a green and cloudy pool even after pool shocking? And then you asked your self what did I do wrong?

Here are some reasons why even after shocking you may still have a green and cloudy pool:

  • Water balance

Your pH level might be too high. Make sure everything is in good balance. Having low or high on pH, chlorine or alkalinity is not good to make sure everything is all balance. If your pool water is not balanced it can make your pool water still green and cloudy even after shocking.

  • Algae

One reason could also be a serious algae problem.

  • Filter

If water balance is perfectly fine there might be a problem in your pool filter. It may also depend on what type of filter you have.

Types of filter
  • Sand filter

It may take a week or more for the pool to clean thoroughly and make it look clear and clean.

  • Cartridge filter

A cartridge can only handle so much, make sure to clean your cartridge every day to work properly.

  • Diatomaceous Earth (DE) Filter

If having a DE filter still gives you a cloudy or green pool then there are some issues about your DE filter. Things like:
