Cloudy pool water can be caused by many different factors. If the chemicals used to clean the pool water are not balanced, this could be the source. Cloudy pool water can also come from natural occurrences such as heavy rain or winds. If the tools to keep the pool clean are not working, this may cause the water to be milky. In some cases, there could be more than one factor keeping the water from looking clean and clear.

It can be difficult to keep pool water clean. Dirt and pool algae can create cloudy pool water or give the water a green tint. Most people use an assortment of chemicals to keep the water clean. Chlorine, algaecide, and other chemicals have to be used in the right amount based on how much water the pool holds. If there are not enough cleaning chemicals in the pool, it could look murky.

The balance of the potential of Hydrogen (pH) measurement is also an important part of maintaining clean pool water. If the water is too acidic, meaning the pH is low, the pool will be cloudy. If the water is too alkaline, meaning the pH is high, it could also cause cloudy pool water. The pH of the pool should be tested often, especially when the water is not clear.

Weather can also be a factor in cloudy pool water. Storms with heavy rains bring particles down into the pool. If wind is associated with a storm, it may blow trash, grass, and tree leaves into the pool. If there are any trees above the pool, animals will often cause leaves and other debris to fall into the pool, which could cloud the water.

There are many tools that keep pool water clean. These tools include a pool vacuum, pool pump, and filter. The machines work together to keep the water circulating and remove any particles that could cause the water to become milky. If any of these parts quit working, then cloudy pool water is often the result.

Many times, cloudy pool water is the effect of several factors. Most people have to use chemicals, filter, and vacuum the pool to get the water looking clear again. Cloudy pool water also tends to happen when the pool has not been used for a few days or if the pool is being used very often. Covering the pool when it is not used can help keep the water clear.
