This is a repurpose special attention item. Aquariums can be the most beautiful thing in the room but buying a used tank is risky. This fixer is an older tank but was a design that was better than just a square tank. Also the deal was take it so most I would be out would be disposal.
number 1 first thing before even taking a tank is make sure it’s not cracked. Most tanks are pretty stout but there are some that are real thin glass. Not to get into tank engineering and specifications, a solid tank should be evident. Also if the tank has silicone all over it’s probably a pass on it deal.

This unit turned out to be a real quality build. Of course the expense comes from the filter setup and things put inside and of course the salt.
Follow-up to come, the tank holds water and no leaks
