I have a 24 foot above ground round, and have used Hayward Xstream 1.5 horsepower cartridge/pump for about 8 years now. Based on what I've read, I think I was talked into buying a system for a much larger pool than I have. The filter is in bad shape, and I need to replace it. Do you think the Intex Krysal Clear 2500 GPH cartridge filter pump would be sufficient? I'm a little concerned about not having a powerful enough pump, but I also don't want to go overboard, either. This may the last year for our pool, so I want to keep using a cartridge filter, rather than learning how to use a sand or DE system. Thanks for any help.
