What size pool is this for? I have a 24' round pool that is 4' deep.

A  Answered on 7/8/2018 by InyoPools Product Specialist Lennox H.

Hi, Zelda. This system has a flow rate of 1800 GPH. It will provide sufficient filtration water flow for a 24' round above ground pool. It will not be sufficient to operate an automatic cleaner.
