Welcome to Reef Central!
Thank you for your message. It looks like you have the opportunity to really build something special!
I am biased, but I love big tanks! My main display is 8' wide x 4' high x 3.6' deep. Based upon what you wrote, I have several suggestions, thoughts and concerns. It is difficult for me to put them all in writing tonight. One concern is that your fish room will be so far away from the main display. It adds another level of potential issues, in the event something went wrong. IMO, you'd still want a sump beneath your tank and some filtration hidden in cabinetry.
Ok- good point about the sump. Im working with a few companies to get bids, ideas on plumbing etc. IVe contacted some of the famous national vendors that have TV shows online to get ideas and cost breakdowns from them. Not sure how the community feels about these guys but they seem professional and do installations on some big tanks so at the very least, Id like to get their input on things. Havent decided on a final builder/installer.
The location of the tank looks fantastic. If you can create access to the tank from both sides, it will certainly help with maintenance.
Tank will have access from all 4 sides. Planning on a hood that will elevate to allow access. Final plans tbd
In the fish wall, as well as the fish room, I would make sure you have plenty of dedicated circuits "can't have too many", drains and if you can, perhaps an exhaust fan in the soffit above the tank. Another thing you might want to consider in the soffit is a mini split or separate a/c that cools the soffit and your tank. I chose to go this route for my fish room instead of a separate chiller.
we will put tons and tons of electrical in the fish room and near the tank. Some dedicated water as well as drains. Probably doing a dedicated AC unit for the room as well- Something similar to what I will have in the wine cellar. The actual location of the support room is about 25 feet away but we will plumb everything with PVC in the slab
You should try to decide upfront, fish only with live rock, or reef. With a tank of this depth, it will help you make decisions as to the type of lighting you will want to go with - given space requirements, coral requirements, heat, etc.
I posted on this already. Most likely will do fish only.
You'll get all sorts of opinions here about glass vs. acrylic. I chose to go with glass. It is more expensive and a lot heavier than acrylic. My main reasonings for going with glass was a fear of getting scratches. My tank is in my living room and I can't afford to have it dirty or scratched. It wasn't but a couple of years ago, I bid out my tank with a dozen companies, both glass and acrylic across the country. I will be able to share estimates with you.
Originally I was going to do some funky shapes and curves etc but now, Ive narrowed it down to just a rectangular tank so glass is an option. I dont want scratches. does Glass look as good? all ive seen are acrylic tanks lately.
I'd be happy to answer any questions you have and will think about other suggestions for you. If you and your wife wanted to take a drive down to Tucson, I'd also be happy to show you my system and go over the pros/cons with you in person. I could also have a couple of other knowledgeable hobbyists over to answer any questions or share with you there two cents. You'll probably find a lot of answers on my build thread. Like you, I waited to build this system until a time in my life where I would not have to cut corners and could afford quality components.
Appreciate the hospitality and yes, I would love to visit. Ill contact you and arrange a time to come down.
Good luck with everything and have fun with the process!
