I went to Lowe's to look for some pool filter sand for a substrate, and found, in the pool section, 25 lbs of "diatomaceous earth", which I assumed had to be the same thing. Naturally I researched it on the internet when I got home, just to make sure, and only found reference to it as used in filters to trap very fine particles. It's cool that it's made of ancient ground-up invertebrates and all, but I'm looking for a substrate. I just wanted to confirm that this would be Bad for that purpose before taking it back. It was about twice as expensive as people generally quote for pfs, anyway ($10 for the 25 lbs). It especially sounds like it would wreak havoc on my shrimp. .
