Lost my mind....or, here we go again!

[Aquattro]

So after 2 years of struggling with my tank, I'm shutting it down. Right after I get the new 180 set up, which will be a couple of months. I just bought a complete system locally, but will need to drill the tank and build a new stand to fit my gear.

Question for all the 180+ crowd...what did you do that made the setup nice, or what would you have done different?

I've got 2 Tunze 6100s on a controller, ER skimmer, big DIY Ca reactor, Zeo already.
Things to look at are drain locations, 1 or 2 drains, durso vs herbie, stand concepts, etc....anything you can think of that I might not have?
