Thickness of the plywood depends on the size of the tank. There are plenty of plans out there for tanks ranging from 300 to a couple thousand gallons. It seems you have to go bigger than 350ish gallons to make it worthwhile.
To seal the tank a lot of folks have been using Rubberize It. https://www.rubberizeit.com/
