DE. That's what I use. It's cheap, generic and available everywhere. Plus it's effective. I know nothing about aqua perl.

I think I may have put to much DE in the skimmer. Gauge usually registers around 15-16 psi, now I am up to 22 psi.
Picked up a large 16 ounce cup and filled a little over half full.

Should I or can I backwash and start over with lesser amount?

thanks

CJ,
Just backwash to get rid of it. And when you add more, add 1/4 of what your added (or less), wait 20 minutes and see if your pressure went up. You want it to rise about 1lb.

Thanks CarlD, backwashed and added 1/3 cup,right on target.
