Hi all. Hopefully this site can help me a bit as I am a complete newbie to pools. HAHA. I managed to snag a rental house with a pool and now I am trying to keep it going since my family is going crazy not being able to use it.

Anyways, I think I have a bad filter cartridge but I am not sure. Are there any symptoms to a bad cartridge? I would normally replace it but it is a few hundred dollars at the local pool store.


Thanks for any info you can spare.
