Sorry if this has already been asked in the thread, but I just got done with sifting an entire bag of Napa (and I'm tired!), and only came away with enough for one pond basket. 2 hours later, and a little DE in my eyes.... I wanted to ask:
1) if there's an easier way to sift it? I ended up sifting with a pond basket, as my 1/4 sieve wasn't getting anything

2) does one pond basket of sifted DE per bag of Napa seem right?
3) what can handle being in this stuff unsifted, if anything, and for how long?
I repotted my "practice" silver maple ROR this afternoon with my resulting soil. Was hoping to get several repotted to test out how they do right before
@sorce 's full moon, but I only have 2 more bags of Napa to sift through.
