Life of Sand Filter?

[Mwil3]

Your sand NEVER needs to be replaced unless you've gunked it up with Bacquacil or something equally bad. I've been using the same sand for 9 years, and my fellow moderators have been using theirs for longer and shorter amounts. As the sand gets older and dirtier, it filters better than it does when "new" (remember: your sand is far older than you are or will ever be).

Thanks Carl....I guess that was just another way for "the man" to get my money.
