When I clean my CARTRIDGE filter - lots of bug bits and hair come shooting out with the water. (I use a jet stream attachment on the hose as suggested.) I noticed this last time (the second time I've cleaned my new filter) that once I hose off the dirt and outside gunk - deep within the pleats (if I actually separate each pleat) I see LOTS of bits and pieces of stuff, top and bottom. It even seems as if there is stuff BETWEEN the pleats on the INSIDE of some pleats. Is this normal?
And do I need to SCOUR or using a finger or brush somehow remove every bit of stuff in the pleats?
I think my filter is a bit oversized for my pool so I haven't seen any significant rise in the pressure gauge. I just cleaned it because it had been a couple of months into the season since the last time I hosed it off.
