I'm trying to get my pool up and going. It is clear enough to see the bottom and and I started to vacuum last night. I was getting the dirt right back in through all of my return lines. I have 4 Pleatco PA137 cartridge filters that I bought 2 years ago. Last night I opened the pod after I noticed this and they were quite dirty. I cleaned them up good with my aqua comb. Ran the pump until this afternoon until I could try again. Just tried again and got the same thing. The cartridges weren't that dirty at all. They still have the bands in tact and still look to be in great shape. Any idea if I need new filters or if it is something else I could do? I would have thought cartridges would last longer than 2 years.
Thanks for the help!
