What is this soft silica looking stuff in my filter?

[fwb]

My past few filter cleanings had a significant amount of this stuff that looks like diaper silica, soft and rubbery to the touch. Any ideas about where it's coming from? Hadn't seen it in past years and if I could prevent it my filter would be much happier.

No idea what that is or where it may be coming from. Have you checked around on the deck or in the planting areas to see if any might be there? If you let it dry out, does the size or texture of it change?

Maybe try putting a hairnet or skimmer sock in your skimmer basket to see if it catches it there before getting into the filter.

That does look like diaper gel! Any babies in the pool lately?

Nope, no one in the pool actually.
