So I rented a house with a pool thinking it would be a great summer adventure...

I've come to a problem. I have a nautilus NS-36 (which I understand is a pretty darn old unit) DE filter. After I backwashed it, I made a mistake I think. I misread the directions, and added the powdered DE straight to the skimmer on the side of the pool. Soon, I started to see white plumes coming out of my return jets

I don't think that this should be happening.....
