Ensuring that the filter can handle the size of your pool and that the pump isn’t oversized, is crucial to figuring out whether or not the water’s being cleaned effectively or not. Pool water can be murky because the sand filter is not working properly. This can be verified by simply finding any deposit of sand at the bottom of the pool. Low chlorine or too high of a pH level, could also be failing to kill off algae or fight bacteria quickly enough. Murky water is also a first sign of the early stages of algae growth before it begins blooms and the cloudy appearance can also be the result of dead algae. Ideally you will want to be able to see a quarter at the bottom of the pool without much difficulty.
Purchasing a new filter will resolve the mechanical issue, but if it’s a chemical imbalance problem make sure to use a clarifier and regularly pool shock. Don’t seek bargain practice when it comes to pool shock though since the chemicals in cheaper products tend to be weaker. Using a swimming pool clarifier will help to remove any particles causing the water to become murky or cloudy. Imbalance in the calcium hardness and pH levels are two additional reasons for murky water. If the calcium content in your pool is too high, consider replacing the water in your pool with a fresher water source with lower calcium hardness levels. Increasing or decreasing the pH levels in your pool should be done gradually to avoid overshooting your desired result. Having the filter run eight to ten hours a day is helpful in maintaining the clear appearance of your pool’s water and is a great preventative measure to practice daily.
