Milky or cloudy swimming pool water can be a challenging problem to deal with. This is generally because it is difficult to know what is causing this unattractive discoloration of the water. One of the best tactics you can use is to try multiple possible solutions, starting with the most manageable or the most likely. Eventually, one of these solutions should be effective at treating the milky or cloudy water that has formed inside your swimming pool.
Remove debris from your pool water using a pool skimmer. Surface debris can be responsible for cloudy water.
Vacuum the floor of your pool using a pool vacuum cleaner. Built-up debris on the pool floor can be causing the milky or cloudy water.
Uncover your pool. The pool cover might be blocking UV rays, which are a natural way to kill bacteria that can cause cloudy water.
Jump in the water and swim around. It might seem unappealing to jump into milky or cloudy water, but lack of water movement may be causing the problem.
Remove any pool toys that have been floating in the water for several days or weeks. These toys could have a buildup of bacteria that are causing the cloudy water.
Balance the chemicals and pH content of the pool. Different areas and types of pools will require different pool chemicals. Check with your local pool supplier to obtain the proper kits for balancing your pool water.
