One thing you may want to do is leave room to expand. Fishkeepers have a tendency to want the next big thing in a couple months. Maybe make it so you can swap out the 3 10's with 3 20H's. Just be sure to leave enough room to do maintenance.
You could probably get away with 1/2" plywood too but I would go with 3/4" just to be safe and keep everything sturdy.
Great thanks for all the help and info!! This weekend I hope we can go out and get the wood!!!
also will get sealant! I should leave a little room for other tanks it would be my "fry shelf". Going to be great though excited
