I couldn't sleep so here are the results.
(This what he says)
These tanks actually sat on top of each others glass work. It was actually pretty scary looking. If i recall correctly, there is 6 baffles on the sump
The tank is drilled with an overflow. The sump is also drilled for a return.
I have the stand results (bones and still rough draft till next week)
