It's a great question. Originally I was working with a few fish consultants and installers and we were going to do just a standard sump. A separate skimmer, separate refugium, etc etc. everything was going to fit nicely in the room but it was going to be individual pieces. Problem was I just wasn't satisfied with the esthetics of it all. It looked too choppy, too thrown together. I wanted something more esthetic and pleasing to the eye. I eventually found the Dreambox and Royal Exclusive but by that time, the framing and doors were already up.
I spoke to my contractor to redo the doors but then the problem was if we did bifold doors, to open the center of the fish room, then you lose climate control. The entire fish room is on a dedicated AC unit to keep the room at proper temperature instead of it getting hot in the arizona summers.
We also discussed having the entire garage air conditioned but getting a proper seal on the garage doors is problematic and in the summer months, I would lose a lot of the cold air to leaks to the outside.
Not that the sump is actuslly here, I might revisit the idea of a single door on either side- right and left, and then some sort of roll up or bifold doors in the middle. I don't think my contractor envisioned what the sump would look like so he might have some other ideas.
I'm not a fan of spending all this money and hiding the sump behind closed doors so let's say this part might still be pending.
