Randy, I've been watching and waiting. I know these filters well.

When you opened the filter to clean it, did you check out the 'tube sheets'. the plastic disks that hold the fingers and secure the gasket?

Improper bumping can break them My 'use and care for DE filters is stickied here, please give it a read.

The other thing that struck me is that the debris on the floor isn't white (DE is) and may be dead algae that has settled to the bottom when the filter is off.

Sounds like the pool water still contains algae.

Once you rid the pool of algae, see if the problem persists.

We'll be here to help
