The tank is so large he can dive in to place corals and do regular maintenance
You do have a good point though...
My tank is exactly the same size. And the back is in the garage...with a platform. Almost the same setup...kind of crazy actually.
Right now, my front access is bolted shut. Reason is that Its tweaked for some reason and my furnace was pulling humidity into the house. Need to figure out a way to get it sealed, but still be able to open it.
And let me tell you , I HATE IT!!! I don't even have fish in it and its a pain in the butt. Yesterday, it took me FOREVER to clean the front of the tank from the back. Up down, up down, around the front to see what I missed over and over.
Now to think of placing corals, moving corals/rocks, feeding, etc...can't imagine wanting to leave it this way. Yes it may look good, but you can do some unique thing with the front too.
Without access from the front, I wouldn't even do it. It would put me in an early grave.
But its your tank. And Im sure it will be awesome and am looking forward to seeing it come together. Your going to love all that room behind the tank. Just be prepared that whenever anyone comes over, they will want to go back there to check it out.
Seems like people are more excited to see whats behind the tank than whats in it.
