The recommended number of hours to run your pool pump each day depends on a few factors, including the size of your pool, the temperature and weather conditions, and the amount of usage the pool receives.
As a general rule of thumb, it's recommended to run the pool pump for at least 8-12 hours per day during the swimming season. This allows the water to circulate and filter properly, and helps to maintain the proper chemical balance.
However, if the weather is particularly hot or if the pool is used frequently, you may need to run the pump for longer to ensure the water stays clean and clear.
You can also consider a variable speed pool pump that can run at different speeds and for different periods of time. This can save energy and money.
It's also a good idea to consult with a professional pool service or pool equipment supplier to get a personalized recommendation for your specific pool.
