Okay, i have a large tall octagon tank, and im pretty sure its around 30 gallons but i need to know how to measure the gallons. Can anyone help me out on that, and no i do not know the history of this tank but i went to a fish store the other day and the owner there told me that i can get it tested there for copper, can it be done? And can i use this octagon tank?
