I was hoping someone could help me. I bought a new aluminum 80 scuba tank on July 28, 2001 at which time it was filled with air. I used it for one very short dive that same week. Most of that original air is still in the tank. My question is, do I need to do anything special before going to get the tank refilled? I was wondering if I needed to get the old air out first?
Thanks for any help I can get.
