Cloudy Pool Water: Get Your Water Back to Clear

Cleaning Cloudy Pool Water

It doesn’t take much for cloudy pool water to begin developing in your pool, and if left untreated, it can really create an unappealing swimming environment. Cloudy, dirty looking pool water can develop for a variety of reasons, including chlorine levels that are too low, problems with the pool pump and filtration system, or simply because the pool is being used more during the summer and needs to be cleaned. No matter what the reason, it’s easy to get even the cloudiest pool water back to the attractive, crystal clear look that you are used to.

Tools You’ll Need:

Step 1. Check the pool chemicals


The first step when you need to get rid of cloudy pool water is to check the pool chemicals, as having them be even just a little bit off can lead to your pool water clouding up. Use a pool water test kit and take note of what your current chlorine level is, as not having enough chlorine is the most common cause of cloudy pool water. When there is a combination of increased usage and not enough chlorine, all the germs and debris that would normally be broken down and flushed out with your pool pump are left to sit and build up in the pool. Adjust your pool chlorine as needed and use a pool clarifier as well to make sure that your pool water is properly balanced in order to clear up your cloudy problem.

Step 2. Check the pool pump & filter


When it comes to getting rid of cloudy pool water, sometimes checking the chemicals is just half the battle! It’s also a good idea to make sure that the pool pump and filtration system are clean and functioning at their optimum level. The easiest way to do this is to check the filter pressure gauge, and if it’s lower than optimum operation levels according to what is listed in your operations manual, then that means it’s time to clean or replace the filter.

Cartridge pool filters can be removed from their housing and gently cleaned with your garden hose, or replaced altogether if they’ve become damaged or have simply worn out from regular use. Sand filters and DE filters are cleaned by setting the pump to the Backwash setting and running the cloudy water through the sand or DE until any debris is removed.

Step 3. Replace worn out or damaged parts




If the pressure doesn’t return to normal after cleaning your pool’s filtration system and your pool water is still cloudy, you may need to replace your pool pump, motor or filter.

Additional signs that it may be time to replace, rather than repair a pool pump:

  1. Leaking water
    If your pool pump begins to leak water, that’s a sure sign that it needs to be replaced right way, as it could cause damage to your electrical system and pool if not taken care of. Check the area around your pump and the pump itself for signs of water leaking.

  2. Losing Power
    If you are experiencing poor power levels with your pump and have already tried cleaning the filter for improved performance, then the pump motor may simply have worn out. Check with the manufacturer or the owners manual for help.

  3. Sucking in Air
    If you start to see bubbles forming around the pool vents and in the water, this means that your pool pump is likely pulling in too much air due to a low water level from a leak in the plumbing, or a leak in the pool pump itself. Check the pump for damage or leaks when it’s turned off.

Once you’ve cleared up your problem with cloudy pool water, keep the pool clean by checking your pool chemicals often and maintaining balanced levels all season long. This will help to ensure your pool will be clean and ready to go all throughout the warm summer months.
