Deep Blue can be a bit of pain to deal with... we ended up getting it replaced... but it was definitely a big hassle to get to that point. Also we still had the tank new at the store, so it never had water. We have been a bit nervous to carry the Edge tanks since that incident. I'm going to be very curious to see what they offer to do for you. I feel like they should do a replacement on the tank... but you never know =/ Either way I wish you the best of luck! Hopefully it will be good news.
