New to sw, have a question about my sand..

[Madreefer]

Do you guys really think that the so called live sand they sell is live or have any beneficial bacteria in it after sitting in those bags for a long time? I don't. Gimmick. But that's just my negative opinion. I'd rinse it. Only time I wouldn't is if a buddy took a cup or so out of his well established tank. Now that's live sand to me
