Thanks everyone I appreciate the comments!
Now comes the real hard part of dismanteling the old tank, got all the water and most of the sand out last night, now I'm gonna have to cut the bulkheads off today and try to get the beast outside to wash it out and store it. Old tank is a 5'x3'x20" 3/4" acrylic so heavy as all get out. Then I need to finish the new tank stand and canopy so my wife will stop bugging me.
The new tank is in our veterinary clinic in our lobby and people are loving it, especially kids.
