What was the name of the bank you must have robbed to afford this
...I won't tell anyone...
GREAT TANK....I know of a guy who lives in Long Grove, IL and his tank was so HUGE that he built an addition to the house, floor reinforced steel girders and then needed a crane to put the monster in its place. All this was done with the roof off, once the crane placed the tank, they put the roof on. His light set-up is much like yours. Only it slides to the side behind the scenes, less stress with an overhead runner system.
His skimmer is about 6 or 7 feet tall.
Personally I have dreamed of a tank exactly that size....30 inches high is more than enough but I am a fan of deep sand beds...I just like the look. Are you going bare bottom (the tank, not you
)...I hate when you can't get down to the bottom of the tank without a ton of acrobatics.
Good luck with an AWESOME project....can't wait to see it filled.
