How to fix a green pool
Decrease your pH level
Add super shock chlorine
Next you'll need to give your pool a shock dosing of chlorine. The stronger levels of a super shock product will quickly kill or neutralise any organic substances in your pool. The instructions on your product will show you how much you need to use. It's also good to use after a very heavy period of rain or having lots of people in your pool.
Clear up the water
Kill off any algae
