I did not like the last reiteration of the 120 so I broke it down, soaked new wood and went another direction. I unfortunately mauled a perfect piece of wood I had planned and then had to use another piece instead. That's okay though, because I had to make a fair no# of changes to the scape anyways. It's a bit like the 180 ATM. 180 is more open than this tank, but I may end up going more a dutch route with that tank and moving this tank into a more low growing species type of tank.
