Just about an hour ago I was looking my tank over and noticed what appeared at first to be some hair. After inspecting it closer and running my finger over it I realized that it was a crack. I followed the crack and it turns out it goes in a complete circle around the neck. I looked the tank over some more and found another smaller crack at the bottom. It looks like I'm either going to have to get a new tank or rehydro this one just to be safe. So, remember to always check your tank at frequent intervals -like before and after play days or every week or two- because you might just spot a problem before it's too late! Nobody wants a hunk of metal, wrapped or not, to be flying at their head.
