Been awhile since I've done any work on the tank or updated this thread. I'm getting ready to tackle the project again.
Equipment wise I'd say I'm about 95% complete. Construction wise probably about 30%. Then there's still the matters of live rock, sand, etc...
So I'm going to be focusing on getting the stand and canopy complete. I'll be working on the stand first. Instead of doors I'm planning on removable panels held in place by magnets (McMaster 1745A15).
I'm going to take some advice from CTripi and make the door panels from MDF, then seal and paint them. To prevent the edges from getting banged up I'm planning to trim them with hardwood. Everything will be flush on the outside of the stand. Everything needs to be airtight for my air exchange system to work efficiently so I'm going to weather strip around all 4 sides of the panel openings on the stand.
Here's a cross section looking from the top down.

The orange hatching is the MDF panel, blue hatching is the hardwood, and the solid hatching is the weather stripping. The opposite side of the door (and top and bottom) will all look the same. I think this should do the trick on keeping it air tight, if anyone else has an idea let me know.
