Just sharing my experience here - I finally shut down the pool this past week and opened up my cartridge filter for its first cleaning since it was installed the first week of June. I've continued using skimmer socks and have a pre-filter which pulls out a lot of the heavy stuff that comes in through the main drain.
After over five months of use I was expecting the cartridges to be significantly dirtier, as my 36sqft FNS Plus needed to be back washed approximately every 30 days. I was able to clean up the cartridges in about 30 minutes. This filter conversion experience has been incredible, the flow is much improved and the pool appears much cleaner.
Anway, we'll see if I'm as ecstatic after opening the pool in the spring.
