What Diatomaceous Earth (DE) should be used or avoided with DE filters? I haven't found very helpful information by googling similar questions. I tried to use food grade DE in my DE filter and quickly learned that I should probably stick to the DE that is labeled is sold for pool filtration. Has anyone had success or failures with certain brands of DE? Any recommendations or warnings are greatly appreciated.

You've already discovered the only real caution I would give.
Anything sold for pools will work.
I use the cellulose DE replacement. I don't know that it filters any better than DE, but it is biodegradable. And it does biodegrade in the filter if you leave it too long and gets sticky so it doesn't backwash well. But since I just open things up and hose the screens off it's not a big deal to me. Anyway, I've discharged all over the lawn and there is no white crust like there is with DE.
