I have a 220 gallon aquarium made by All Glass Aquarium I'd sell for $400. 6'Wx24"Dx29"H. Not drilled, but I do have two Synergy Reef Shadow Boxes for it, sold separate. Silicon is perfect(no leaks), never had copper in it, never been outside. Water was in it 6 months ago. I’m going to a 300 gal. No stand or sump. Call me and leave message. Robert at 303 775 9867
