Of course, that's only if your pool is properly maintained and that includes running the pump to filter the water. But does the pump have to run all the time, as in 24 hours a day? Before you just turn it on and leave it, let's first talk about what a pool pump actually does.
The pump is the main part of the swimming pool circulation system. When it's running, it keeps the water moving; otherwise the water would become stagnant and things like algae and bacteria could grow. The pump also clears debris from the water and keeps those pool chemicals mixed by pushing water through the filtration system.
Many variables determine how much time you need to run the filtration system, including the size of the pool and how you use it. But the bottom line is 100 percent of your pool's water must filter through the system at least once a day — something called turnover rate.
