Do you want fast or slow turnover for system efficiency in a 15x30 above ground pool?

Answer 1

i prefer a slower turnover for several reasons... primarily because slower water travel through the filter tends to give you a better single pass cleaning and isn't as hard on the cartridge pleats. most important is to remember to clean the filter(s) when the pressure has risen 5-7 psi over the clean pressure. and don't forget to degrease the cartridges occasionally to remove body oils etc...

The water speed through the filter should be low for best filtration. This means that your pump and filter need to properly sized in proportion to each other. A high power pump will not improve the clarity of the water if you're using an undersized filter with it.

A good rule of thumb is to size the pump so that you turn over the entire volume of water in the pool in 3-4 hours. Generally, you'll need the pump on 4-8 hours a day anyway, so you should get around two turns of the water per day, which is perfect. Then, use the pump rate (gallons per minute) to select the proper size filter (in gallons per minute). Using this method, you will ensure that you're getting good filtration, good water circulation, and not wasting electricity.
