Pump basket seal powder

Seriously... Looks like my pump basket is doing cocaine lines and I got no invite lol...

Anyways, what is this white flaky dust that was around the top of my pump basket seal? I’ve never seen it before.

Did you add DE to your cartridge filter?

What’s DE?
I’ve only added acid to it for past 2 months. Other levels are good.

Diatomaceous Earth. It's used in some filters.
