I recently purchased a Camelbak BFM and used it for the first time today. I love the bag, but the taste of the water from the reservoir is TERRIBLE!!!! Just to give an idea of houw bad the taste was, my dog would not drink it. After adding a powdered drink mix it was still awful. Any one have any expirence with this, or have advise to fix it? Thanks for any info. <img src="/images/graemlins/smile.gif" alt="" />
