DE leaking into pool

[Jakebear]

I have a Hayward Perflex DE filter --- a small "Puff" of DE after bumping and pump start is normal, and happens because the fingers are not completely coated with the filter media.

I'm not familiar with the Apollo filter but I think the principals are the same.

This is way more than a "puff" and it never did it before in the past 6 years we have lived here.
