I am looking at a monster tank that is for sale in my area. It is 84 inchs x 34 inchs X 39 inchs tall. It is all 3/4" glass with double layers on the front back and bottom ( 2 x 3/4 " ). The sides are only one layer. The bottom also has a layer of plywood. This is a brand new tank that has been drilled as a reef tank with 6 overflows.Also included is a 90 gallon sump with 2 pumps and a metal stand. I have never had a tank this size or known anyone personally that has and am gunshy of jumping into a purchase like this without getting as much info as possible. My main question is if the glass thickness is normal and second if having six overflows will effect the strength of the bottm glass. Also is there any reason that a tank set up to be a reef tank could not be used for freshwater. Any info will be greatly apretiated.Thanks in advance for any responces.
