400 gallon project

[Delphinus]

Thanks for the info. I'm looking at your photos and it's helping me plan out the "corner viewing" aspect I was hoping to acheive with my 280g as well. I wasn't sure if I was going to be supporting the wall framing to the ceiling above, or what. I might need to consult a builder, I'm not sure what's kosher for suspending things on the floor above. I like how you've solved that with the wall flush to the right-hand side tank wall.

A couple more questions.. what's your floor, is it concrete? If so how is the stand attached to the floor at the bottom?

To make the stand open at the back (where the sump is sitting) without a bottom cross bar member (or whatever it's called) did you have to put any diagonal bracing, or additional posts under the middle of the tank or anything like that?

Thanks once again for the info. Very helpful!!
