is there a way to see if Diatomaceous Earth has the right quality? There are different colors like grey/brownish/white
Now I've read different views on it, one says:
" The white DE is considered higher grade because it IS white....
Different colored DE means it came from different sources.
I've seen grey, reddish and white. THe reddish one was being sold as animal grade DE (good for animal feed but not certified for human consumption)"
"few different types of DE,here [...] you can get the brown or white.The brown is more gritty and the white finer. I tried both for curing worms and parasites the white DE did not help after switching to brown within 1 day worm eggs were expelled.
Both types food grade[...] would probably explain why some people say it doesn’t work"
Anyone with personal experience on that subject so far?
