The return has a very powerful flow now. But i can't be sure it's on filter and not recirculate.
Let it filter awhile. You could hook up and vacuum. If the bottom is dirty, the psi should rise if you're actually on the filter setting. You could throw in another 1/4 cup of DE to see if the psi bumps up but if the bottom needs to be vacuumed, I'd go with the vacuum test first. If it's on "recirculate", you'll see the dirt going right back in the pool as you vacuum.
