With regular maintenance, a pool at your home can be relatively easy to take care of. No matter how much you keep up with maintenance and your pool’s chemistry, there are still times when the water will be stubborn and stay cloudy. A lot of pool owners have this problem, especially during the summer.

There are plenty of possible causes, but only a few common ones. Keep in mind this discussion does not refer to a green cloudiness; this coloring is the result of an algae bloom. White or earth-colored cloudiness is a completely different issue, and diagnosing the problem takes ruling out a lot of options.

Sediment Can Be Hiding

Keeping your pool clean may seem to be the obvious answer, but sometimes sediment can look almost identical to the pool’s bottom surface. Scrub the walls, vacuum the bottom thoroughly, skim the surface and run the pump for twenty or more hours to see if the water becomes clearer.

Improper Filtration

Make sure that your cartridge filter is cleaned and tightly fit. Check to make sure your DE or sand filter has a proper fill level. You should calculate whether or not your pump has been running long enough for the filter to finish the job.

Some filtration problems can result from a ruptured filter or one that allows water to bypass its filtration element. When this happens, you will see an earthy buildup on the bottom of the pools and near the return jet. Other similar problems can occur when there is a leak in the pipe near the pump. Air bubbles will become trapped in the water and result in it looking milky.

There is also the possibility that your filter may simply be past its prime and in need of replacement.

Unbalanced Chemistry

If you regularly test your pool water, there is still a chance you may have missed something. Some tests are more accurate than others, and pool owners can forget to worry about smaller aspects like alkalinity.

One of the biggest problems pool owners face is a compound called chloramine. Chloramine results when chlorine comes in contact with contaminants in the pool like suntan lotion, certain fabrics, oils from skin and other substances that enter the pool on a regular basis. The chloramine will interfere with the sanitizing agent in chlorine and disrupt it.

Using a non-chlorine shock product will oxidize these compounds before chloramine can be formed. This process is especially important in the summer when the pool sees more use and will come into contact with more suntan lotion and similar substances.

Common Chemical Mistakes

Some cloudiness is caused by an overuse or improper use of chemicals. For instance, pool owners using PHMB products such as Baquacil or Softswim should never add chlorine or copper algaecide to their pools. PHMB pools also need to be drained every three years because of the nature of the chemicals.

Another type of mistake is to add sodium bicarbonate and calcium chloride to the pool around the same time. These compounds will naturally react to form a salt precipitate that will cloud your water. Using too much of either of these additives will have a similar effect.

All these reasons are why it is important to have your filtration system and pool chemistry checked by a professional Rio Vista pool service. Visit our residential pool services page to find out more.
