FS 75 Gallon Oceanic Drilled minor leak

Hi,
I picked this tank up a few years ago from Hung over at Sea of Marvels.  It was drilled for three 1" bulkheads and has an acrylic shelf creating a totally silent "Bean Animal" style overflow.  For more information about that just google it, but it worked flawlessly and my new tank has a version of the same system on it.
The tank developed a small leak a few inches from the top in one of seams.  By small I mean I barely noticed the extra salt creep and had the tank running fine for a few months after I discovered it.  Its a few drops a week or something.
Anyway, its for sale...totally obo...ALL OFFERS CONSIDERED...its a nice tank but will need attention due to the leak.
