I ordered my DE from custummilling.com and no you don't want to get it at the pool supply store at all...that would be the wrong stuff. It should be pure white powdery looking. Should not have any tinge of brown color at all. I believe my bag also said fossil flour on it. They don't sell it at many feed stores either I have noticed so It's just safer getting it online. It was 50.00 but it has lasted me all year. WELL worth the money to KNOW your getting the right stuff and that it's safe for your chickens
Good luck!
