Subj : 120 Gallon tank To : Scott Brown From : mark lewis Date : Tue Jun 23 2009 05:53 pm SB> I have a 120 gallon tank that I want to setup, but it does not have SB> a top. Any suggestions of what to use? It's a old tank, so there is SB> no model number to order one for it. Would plexi glass work, or SB> should I have one cut out of glass? you can probably use anything for a top... plexi would be a good place to start... then you can notch it and even hinge it for a frontal area lift up door... plexi is the closest thing to a formed plastic cover you'll get without a mold or finding one that fits that tank's dimensions... glass would be too heavy, IMO... )\/(ark * Origin: (1:3634/12) .
