I had an in ground pool built last year and it came with a cartridge filter. I have had a lot of problems opening the pool this year and one of my complaints has been that the cartridge filter gets dirty and I have to wash it out daily. The builder has offered to come out and exchange the cartridge filter and install a sand filter and pump at no charge.
So my question is...which one is better, sand or cartridge?
