This is the first time I've ever had a question I couldn't find an answer for on the site. I started with new sand this year. I should note that we have high iron well water, however, once it oxidizes it filters out easily.
No problems with the (brand new) pump/filter for the last month. Excessive chlorine loss over the last few days pointed to algae, and so began the slam. I've noticed small amounts of sand under the return before, but today there was an unusual amount. So I sucked it and some bigger debris up and watched the return spit it back out.
Tore the filter down for inspection, and found....
The sand was so filthy I'm surprised it hadn't become sentient. The tiny slits in the laterals (?) Were chock full of debris, but not broken. I backwash and rinse regularly, but to look at this mess you'd never know it.
Is there an issue with the pump pressure not being high enough to flush out all of the junk in the sand? Are the sand particles too big for the pump? Or am I overlooking a simple, common sense detail per usual?

Thank you in advance!
