There must be a better way to wash a pool cartridge filter!

Here's a picture of the cartridge taken apart.

I presume the water flow is up the two holes into the INSIDE of the two
pleated filter cartridges ... but WHAT is that thing sticking up in the
middle doing?

Here is a picture of me trying to wash the larger pleated filter with a
garden hose:

First - own 2 filters. Swap them out and soak overnight.

[if that doesn't work for you, I like their Leisure Time filter
cleaner-- and I've always gotten good service from poolandspa.com]

I've forgotten [hot tub] filters in their soak for a week or so with
no ill effects.

They sell a wand that is supposed to clean pleated filters better, but
I do mine in a deep sink with a regular hose and warm water. Then
they get dry before their next use. I've been rotating 3
filters for 4 years in my year-round hot tub.

Unfortunately, even after two hours of that, the green slimy sticky gunk
is still on hundreds of the thousands of pleats:

Keep an eye open for a sand filter at a garage sale.
