Reached a small yet large milestone!
Here is the intended home of the aquarium! The sheet of plywood is 4x8 too get some perspective.
After a nearly 2 hour struggle, removing a door, then the external overflow. And then removing handrail it finally made its way into the basement! Minus the overflow, but it maybe a good thing as I can have larger holes drilled for 1.5 inch bulkheads.
It was late and I was tired after the fight, so tonight I will inspect and start the filling!
