Looking good, looks like we may same sump as well, proflex 3. You can see my build I fit a mag 9.5 and a swc 120 skimmer in the third. Mines the Gomes Illuminata build.
Nice build and yours is a little more hardcore than mine!!!
It's a proflex 2, think I'm going to try and squeeze a reef octopus 160 in the third chamber.
