Planning to join you fine men

[PJtree23]

I have a 280 gallon in the works...well total system volume 467 gallons.

In all honesty this may not take form until this time next year when i get a job :bounce1:

Its a 5 foot long by 5 foot long square 2.5 feet deep. The display tank will be a sectioned off 280 gallon display tank. The divider between the display tank and the rest of the volume will be a tinted glass pane with 2 square slots. The next section to follow will be a glass plate creating an eight inch gap with the divider making room for a 46 gallon "sump". The rest of the tank will be partitioned into three even sized sections around 50 gallons by perpendicular dividers 20" apart along the length of the tank.

I know...crazy AIO...yea it is...I'm doing it...

The return will be "bean animal inspired" filling up the "sump" via 1" water level differential. Water will flow via another 1" water level differential into the central 20" wide, 50 gallon section. Within that section will be 5 NextReef MR1 Reactors (2 carbon? 2 bio pellets? 1 RowaPhos?). A TBD skimmer (?). Inputs for sensors (which ones are important???). Inputs from 4 peristaltic pumps. Input from chiller etc...

Comments suggestions? The platform I was planning is a steel frame with black marble on visible surfaces around DT. I am going to build a wall and "fish room" around the unseen 187 gallons.

Lighting...LED all the way...this has to be the solution...and no fans for cooling because I am interested in heat-sink design.

Any comments about the reactors, input sensors and skimmer which is required for a tank of this size?

Thank you!

Edit: stocking, 10 x sail fin tangs, 1 Ritteri nem and a few clowns.

What skimmer is recommended for a 280 gallon tank?

I was thinking about using two smaller units...but maybe one giant one?

I would like to keep individual reactors for each type of media. How many and of what size should I consider?

Tentatively I was thinking 2 skimmers each rated for 200 gallons.

And 5 NextReef MR1 reactors (2 for black diamond carbon, 2 running bioPellets, and 1 with Rowaphos???)

As for the electrical, I was thinking 4 20 amp GFCI boxes??? How much does it cost to have an electrician install them?

Thanks,

PJ

"Join you fine men"? What about the women who reef? I have a 300g and several smaller tanks.

*Update*

More sketches, what do you guys think of the overall design so far? I am not sure how I am going to do the return yet.

I want to go with submersed Eheim return pumps, 2 or 3 of them. Should they be plumed back into the "sump" or directly into the DT? (pros/cons?)

I hope that the images help explain the design well enough. Basically, in Bean-Animal fashion, the water from the DT drops 1" and into the "sump". Then one more inch into the central cistern (3 created by glass dividers going the entire height of the tank).

The theory behind this tank is that the lack of excess pluming will reduce the amount of upkeep required, thus making the tank more feasible in the long run.

Also, I wanted to do a rimless design for the edges of the DT. Anything towards the back of the tank can have any type of bracing. Can I do a hybrid half rimless half braced design?

Recommendations/thoughts appreciated.

A perspective view from the front

Side perspective + side view with flow direction

Top View with flow direction

Initial Tank: 5' x 5' x 2'
Stand: 5' x 5' x 3' (aluminum with black marble facade)
DT: 5' x 3' x 2' (3/4" thick) ~ 225 gallons
"Sump": 5' x 0.5' x 1.667' ~ 32 gallons
Cistern 1 (RODI for ATO and water changes): 1.5' x 1.4' x 2' ~ 31 gallons
Cistern 2 (Skimmer, 3 MR1 reactors +): 2' x 1.4' x 1.6' ~ 34 gallons
Cistern 3 (Salt water for water change, mixed and temp matched to the tank): 1.5' x 1.4' x 2' ~ 31 gallons
All of the tank dividers are going to 3/4" glass installed while the tank is being built.
