Ah, I like your style. Ask for forgiveness not permission
Those look like great sumps.
The MM is well built. If you're going external I think that's the best choice. I'm not sure if they caught up but when I was building my current tank they had an insane back log, months of waiting so I went with something else.
This next tank I'm going all Tunze so I dont need that gap for mp40s behind the tank. with the dimensions of the tank combined with it being in a corner I decided to go internal corner overflow to be safe. Externals are awesome but I've had to fix leaks and its a nightmare if you didn't plan placement right.
If you do go external on that size do yourself a favor and offset to one side or there other incase you need to get to it for a leak or maintenance. I centered my 180g 72x24x24 and it was a nightmare when it ended up leaking. My fault because:
1. I should have strapped/supported the pipes better.
2. I wish I had put some type of seismic flex conduit somewhere in the run to allow for bumps and reduce any leverage from imperfect conduit runs. 1.5" conduit is pretty heavy and strong. I think I got leaks from not having it plumbed perfectly, or possibly moving around below and allowing the conduit to apply pressure to the overflow box resulting in the leak after time. My thought is the pipes possibly werent allowing the box to rest flush/parellel to the back of the tank.
Oh yeah, put your straps where you can access them. I strapped it all up then slid the tank back and couldnt get to any off it.
