Why is my pool cloudy or murky?

It’s one of the most frustrating things that can happen when you’re trying to enjoy a nice swim on a hot day: you jump into your pool only to find that the water is cloudy. It can ruin the whole experience, and leave you feeling grumpy and frustrated. But why does it happen?

There are actually a few different reasons why your pool might be cloudy, and thankfully, there are also a few different ways to fix the problem. Keep reading to learn more about why your pool is cloudy and what you can do to clear it up!

1. pH Level Is Off

One of the most common reasons for a cloudy pool is simply that the pH level is off. If the pH level is too high, it can cause the water to become cloudier. The best way to fix this problem is to use a pH testing kit to test the water and then add chemicals accordingly. You can usually find pH testing kits at your local pool supply store. You can contact our pool service technicians to have it taken care of quickly.

2. Too Much Alkalinity

Another reason why your pool might be cloudy is because there’s too much alkalinity in the water. Similar to pH levels, if there’s too much alkalinity in the water, it can cause it to become murky and unclear. You can test for alkalinity levels using an alkalinity testing kit, which can again be found at most pool supply stores. Once you know how much alkalinity is in the water, you can add chemicals to balance it out or have one of our technicians take care of it.

3. Old or Dirty Pool Filter

Yet another common cause of cloudy pools is dirty or old filter cartridges. If your filter cartridges are dirty or old, they might not be able to do their job properly, which means that dirt and debris could be circulating through your pool instead of being caught by the filter. To solve this problem, simply clean or replace your filter cartridges as necessary. This is something that you should be doing on a regular basis anyway – dirty filter cartridges are one of the most common causes of poor pool water quality!

4. Weather Conditions

Finally, sometimes cloudy pools are simply due to bad weather conditions. If it’s been raining a lot or if there’s been a lot of humidity in the air, that moisture can end up in your pool and make it appear murky. In these cases, there’s not really anything that you can do other than wait for the weather to improve before swimming again. Luckily, this shouldn’t be an issue for long – once the weather clears up, your pool should start looking clearer as well!
