Custom 42 gallon aquarium with sump located in the Denver area. Thick glass (bottom is ¾” with Starphire on 3 sides and eurobracing. Black acrylic glued to back panel. External overflow with 2 drains. Plumbed for 2 closed loops that I ran as alternating gyres using controllable DC pumps. This allows the entire space of the tank to be used for livestock with no wires, pumps, etc. Plumbing is currently configured so that the tank can be set at 45 degrees in a corner, leaving room behind to hide all the support equipment. All told, it makes for an incredibly clean look. Also includes a matching custom enclosed canopy. Selling because I upgraded to a 150g. $300 OBO
