This is only my second summer using this filter, and I closed the pool early this year on 8/18/2022 and when I open it up to clean the cartridges, the bottom cartridge was crack right across the middleand in two pieces now I have to replace and have to buy both top and bottom, I have a core 55 Genarator, a multi cyclone filter and a circupool smartflo variable speed pump 3 hp, set variable speed motor by the book plus the circupool CJ-2750., grant you my pool was clear both summes but see know reason that happen, my pool is 16' x 32' x7' square.

Excellent service and products
