my brother helped me build a 120 gallon tank... ok, he built it based on my blueprints. its 5 feet long, and 2 feet wide and the glass is 3/8 inch thick. he also installed a GFCI outlet and he also built a steel stand to support the tank with adjustable casters.
when he has the time, i'll make him finish the custom hood
so you need to know someone who can hanldle glass and work with silicone. knowing someone who can weld steel is also recommended!
