So i'm a little stumped with sizing my overflow bulkheads for my 185 gallon tank. Also i'm starting to second guess my idea of having it viewable from both sides reason being limited on overflow options and alot more glass to constantly clean. I'm back to looking for other options for my overflow set up. Please help lol i'am still a noob at building a tank but have been in the saltwater hobby for 3 years now and still feel like i know nothing lol.

Plus i'll have to develop my basement accordingly if i choose a tank that is viewed from both sides which makes my house harder to sell down the road

Actually it would be easy to frame in where the tank will sit in the wall, but cleaning all that glass ............... hhmmmmm but i think it is the nicest possible way to do this tank decisions decisions hmmmmmm

4 options:

Center Back OF, Single Corner OF, Dual Corner OF, OF box on the back of the tank.

Crap 5 options, you could do a coast to coast OF with a drain out the back at each end of the back panel.
