OK, we're full of FW - looks about the same level-wise (I think the freakin tank weighs 300 lbs by itself)... guess we'll give it a few days.
This is clear across the basement from the floor drain - the 50 is much closer to it and has zero tilt, go figure. It is the twisting thing I'm worried about as there is a slight front-to-back as well as the end-to-end slope...
I don't want to have the base teetering on stacks of shims...
Yeah I thanked myself for the present - with a hernia!

Plans for the tank are to combine my 50 and 29 into it, and have The One Tank. I'm going to partition off the one end (about 10") with a glass-and-eggcrate divider to make my version of an in-tank refugium.
Time to step up, sure... thanks!

The smaller tanks are jammed with their own success - definitely need more growing and swimming room.
