Hey, where did everyone get their Oynx Sand? I can't seem to find any here in Michigan, and Big Al's wants 7.79 to ship each 15 pound, $12.49 bag. I need 4-5 so this obviosly wont work... Anyway, I heard you can call Seachem and they will ship it to your LFS for $12 total, and not charge you for shipping... anyone have this experience?
