As summer draws near, you have dreams of long, lazy days on a luxurious pool floatie, or perhaps a few wild afternoons playing Marco Polo with the kids. In your dreams, your pool water is crystal clear, sparkly blue, and oh-so beautiful. No one wants to dive into a pool of cloudy water! The good news is that when you have water issues, it’s a pretty easy fix. There are a few main causes for cloudy pool water. Here is your trusty guide to correcting each problem.
The most common culprit for opaque water is low free chlorine (or FC) levels, which means your chlorine is not able to properly sanitize the water. You can find what your FC levels are by deducting the value of the FC from the total chlorine. You should check your chemical levels, and if your free chlorine levels are 3 ppm or your total chlorine levels are greater than 0.5 ppm, you need to shock your pool.
Ammonia or Algae?
In rarer cases, you could have an ammonia or an algae problem. These usually occur at the beginning of summer and they may be a bit more difficult to get rid of. If it’s an ammonia issue, your FC and your Cyanuric acid levels will be close to or at 0 ppm. You’ll need high amounts of chlorine to solve your problem.
The beginning stages of algae growth often cause cloudy pool water. To test for this, you’ll need to do an Overnight Chlorine Loss Test. Add your chlorine at the end of the day after sundown and take your FC reading first thing in the morning. If your FC levels have dropped more than 1 ppm, then unfortunately, you probably have algae. The quicker you catch it, the easier it is to treat. You can also prevent it from reoccurring with an algae preventative.
Other Cloudy Water Culprits
Still can’t find the source of your water’s funkiness? You may be dealing with:
- Improperly balanced chemical levels like: pH, alkalinity, calcium hardness, or stabilizer.
- Not running your filter long enough or clogged cartridges.
- Dust, pollen, rain water, leaves, or other debris that may clog up your filtration system.
