How do I know what size pump and filter I really need?

Your pump and filter will be sized according to the volume of water in your pool. While you might think bigger is better, the truth is that a pool pump that is too big for your pool can cause serious problems, like cloudy water and damaged filters and plumbing. Oversized pumps also waste energy and money.

The main objective of any filtration system is the ability to turn over all the water in your pool at least once within a period of 12 hours at the lowest energy consumption possible. Accomplishing a daily turn over of the body of water in your pool does not necessitate the use of larger pump, to the contrary, the pool water clarity, the plumbing, the equipment and especially your wallet will benefit from a proper sized pump and filter. Avoiding over sized pumps can help avoid unnecessary costs from wasted energy due to resistance and cavitation, will reduce the pressure on the plumbing and equipment leading to less repairs, longer lasting equipment and plumbing which equals more savings for you. It will also allow the filter to remove finer particles from the water it could not when the water was being shoved through the filter media.
