Hey sock, welcome to TR.
This will be a huge undertaking. The following should give you things to consider as you go along. These suggestions are simply my opinion.
Your tank would be around 330 gallons and would require careful planning to be successful. One of the problems would be sufficient flow and variable patterns of flow. You would need to push around 6,600
gph as a minimum, more would be better. You can accomplish this from a variety of sources. The main pump taking water back from the
sump/refugium and several internal pumps like the Koralia from Hydor or Vortec and others. Lighting, as mentioned above, would be challenging but do able. With a tank that size I would consider an
RO/DI unit plumbed into the
sump along with calcium reactor, a kick-butt
skimmer, a UV Sterilizer,
Phosphate reactor and it's likely you'll need a remotely located chiller. Your stand would have to be professionally welded tubular steel powder coated to protect it from corrosion, or marine grade aluminum. It has to hold up under tremendous weight. Just tossing some approximate weight considerations out...
Water = 2,800 lbs
LR = 500 lbs minimum
LS = 600 lbs if you go with 5"
DSB
Tank = 500 lbs estimated if Acrylic, if glass 3x that.
Total = 4,400 lbs 5,400 if glass is used (all estimates)
Plus all the other gear in the stand and the weight of the water in the
sump/refugium.
You'd have to be sure your floor could support the weight, too.
Cleaning the inside of a tank that deep is a real pain in the arm pit.
And then there's the cost of everything. I could see you hitting $30,000 easily.
Just my thoughts as you contemplate your new project.
