A capacitor can be made from two sheets of aluminum foil separated by a sheet of waxed paperIf the sheets of aluminum are 0.31 m by 0.37 m and the waxed paper, of slightly larger dimensions, is of thickness 0.03 mm and dielectric constant kappa 2.5, what is the capacitance of this capacitor?
Plexi-glass may workA lot of hard ware stores carry itHome depot, lowes, etcThey will sometimes cut it for you.
Try the plastic lens that sits on commercial flourescent lightingYou can get it at any hardware store and cut to fit your tank.
