Thanks a million. Yeah I love your tank it's absolutely beautiful. I will probably try to replicate the tank as best as possible though I'll probably leave the back blank because I am nowhere near that artist lol. Amazing job on the tank man and thank again for the help.Haha, don't be sorry, questions are good, better to ask questions than to just assume and mess something up. The plywood is 3/4 inch (birch?) Pretty standard high quality finished wood. 4 sheets of that with 3, 1.5 quart kits of pond armor and of course the glass panel and a lot of screws and silicon. Pictures of the exact brands and types I used should be in the first couple pages if you are trying to follow step by step.
