Anyone use this product? If so, did/do the bottles you purchase come sealed on top with the cap or just the cap alone and no freshness seal? I'm asking, because I just purchased a 12 oz. bottle yesterday with no seal on it, and when I dumped the bacteria in the tank, it didn't look very populated with bacteria for the amount I was anticipating. I paid $35 for that stuff and feel that I got ripped off with a bottle that was deluted with water. Just as a side note; this was the only 12 ounce bottle on the shelf with an unmarked price on it. I'm very suspicious at this point. I'm planning on making a trip back to the store to check one of the other bottles to see if they have seals on them or not. I even called and left a message to the TLC distributer to tell them my concerns and questions. I'd just like to see anyone elses experience using this product as well, before I jump to conclusions. Thanks.
