Do you have a pic of the setup? The value can range from $200-$2000 depending on the equipment, pumps, kind of lighting. Without much detail, the canopy lighting system is prolly a lot of the value. If you shop around you can get a lot of tank for $200-300.
it's 3' tall 3' wide an 2' deepDo you know the tank dimensions? It seems small for 150G from the pics.
Ok so I'm getting a 150 gallon cube tank stand canopy with light was wondering what value it's worth because I'm trading a gun for it and how hard an what do I need to setup the overflow in it
