I just bought a 110g used tank. The sticker has an anchor on it with a mfr date 2013. Is this a perfecto, deep blue pro, or AGA. Wondering for drilling purposes. The deep blue is tempered f,b, and bottom. And the perfecto's supposedly are not tempered anywhere. I believe the AGA's are tempered in some panels. I just don't want this thing to pop if I start drilling it. Any suggestions?
