So 96 x 36 x 28 =~ 400 gallons, nice!
So I'm guessing another custom glass tank?
Since you will have a sump under it and noise will be a concern, I would do this with a BeanAnimal 3-pipe overflow system. I have one running on a 144g tank @ 3000 GPH and it is dead silent, even with every cabinet door open the only thing you hear is the pump (reeflo dart). My fan on my desk makes more noise.
I would recommend an internal overflow box that passes through to an external box on the back of the tank for all the plumbing. Bean told me in one conversation that this is actually the better way to do it vs. his original design (which was done because that was the conditions under which his tank had to be done, I believe). But there are certain considerations to make to ensure it is silent and most tank manufacturers/designers don't have the first clue what works correctly for dead silence.
The what is really nice is that you will have 100% of the tank floor to work with.
I can do calcs and design for you if you like (on the tank as a whole) I love planning out systems.
I like designing sumps and stands also so let me know!
Are you going to start a new thread?
