i have a pebble tech in ground pool with spa about 20,000 gallons i would like to replace my sand filter is this the right one?

A  Answered on 12/9/2020 by InyoPools Product Specialist Hector F.

Hi Sam, if you are not changing the pump or any water features to the pool then as long as your new filter meets or exceeds the GPM(gallons per minute) rating the current filter has then you will be okay. If you do not have that information then there are a few variables to consider when sizing a pool filter. Here is a guide that we put together called "How To Size a Pool Filter" that should assist.
