Shocking your pool sounds dramatic, but it simply means you add chlorine to kill pathogens and other organisms that make swimming unhealthy or unappealing. However, some pool owners are surprised to find that their water is still cloudy even after they shock it. Here are some reasons why this happens.
A Heavy Load of Dead Pathogens
Cloudy water after shocking can be a sign that your pool had an especially heavy load of pathogens and contaminants. The cloudiness is largely a sign of many swimmers getting in and out. You might notice the water clouding up after you’ve thrown a pool party, if it’s been very hot, or there’s been a storm that’s dumped all kinds of contaminants into your pool. If your pool cleaner checks the rest of the pool’s chemistry and finds that it’s balanced, all you or they may need to do is shock the pool a few more times. Your water should be clear after that.
Your Pool Filter Is Faulty
Another reason why your pool water is cloudy is a pool filter that doesn’t work as well as it should. Make sure that the skimmer baskets and strainers are kept clean, and the pressure gauge is where it should be. This gauge lets you know if your filter needs to be cleaned out or backwashed. Your pool filter may also be too old to do its job anymore and may need to be replaced.
Your Pool Shock Is Inferior
Another reason that your water is cloudy after you shock it is that you’re using low-grade shock. This shock isn’t the best to handle the job that you’re asking it to do. Always make sure that the shock you use for your pool is the best quality you can afford.
Very High Calcium
A very high calcium level, which is over 400 parts per million, can make your water cloudy. Different types of shock can prevent very high calcium levels. Consult a pool expert to find out which type of shock is best for your pool.
High pH
The pH of your pool water measures its acidity or alkalinity. When the pH is above 7.4, it may mean that the water is too alkaline. This encourages the buildup of limescale and calcium, which leads to cloudy water.
