Do I need to run my pumper every day?

The pumper is used for the purpose of keeping the water circulating through the filtration systems back into the pool, removing dirt, and dispersing the chemicals evenly. Therefore, running the pump is necessary for the pool. 

Ideally, if you leave the pump running all day, the pool will always be clean and safe. But in reality, that does not seem cost-efficient and is sometimes unnecessary. Therefore, you can let the pump run all day, but divided the running time into around 8 to 10 hours every day. Keep in mind that the operation hour for the pump also depends on the capacity of the machine, the condition of the pool water, and the size of the pool.
