Which Diatomaceous Earth Pool Filter DE is reef safe?

[BrianReefer]

Anyone ever use this stuff in their diatom filter to fight Dino’s? If so, which should I buy? I see a few of them on Amazon. Everyone says buy “pure pool DE” but none of them list ingredients. Suggestions please?

I bought mine from a pool store, I can take a picture of it when I get home.

I've been using the same bag or random pool store DE for about 20 years. I'm starting to run low, so I'll just go back to the pool store and grab another bag that will probably last longer than me! Way cheaper the "aquarium grade" DE!!!

Yes I believe mine was a 40 lb bag for under $30

Any DE will work, its all the same.
