im getting ready to add sand and my LR to my tank and was shopping around for live sand.. i know that it will get stuff from the rocks but i wanna get it anyways.. my question is all the places that i have found around me sells it in bags and it looks really dried out and has been sitting on the shelf for awhile.. question being wouldn't everything in there be dead from getting dry or would there still be stuff living in there? any info would be great thanks!
