I know that tag. It is the same tag used by the makers that sell the tanks walmart carries, like their 55 gallon kit. From that I don't know what else to say. I just recognized the ancor. Should be ok I would think. It is not Oceanic and I don't think All-Glass.
So far it has cleaned up well and has passed the leak test. I'll probably let it sit full of water for another day or two before bringing it inside to be sure. Thanks for the replies.
