There seems to be so much information out there. I had a 240 acrylic that i have since got rid of. The fish are currenrly living in a kiddie pool. I'm nearing the compleation of my plywood/glass tank. I have doube 3/4 plywood on the bottom, back and one side. The front and other side are for viewing. The front consists of three sections of glass. Once i screw the first board down do i screw the sanded plywood to it or do something else. I plan on using the Ames elasto barrier. Once i figure out the wood i was going to caulk the joints and install the glass befor i use the Ames product. Is that correct. I could really use a step by step.
