I recently purchased a tank off of CL and after bringing it home and filling it up to test it out I notice something peculiar, it looked like air pockets along the seams of the tank. I'll attach pictures.
Could someone with more experience tell me if this is normal or if I bought a bad tank?
Furthermore I was told the tank was fairly new (a of couple of months old), however during cleaning and closely inspecting the tank I noticed a small sticker neatly hidden that said "Built by M.C. Dec 2005", did the guy lie?
