Well,
The tank is 12ft x 4 ft x 4 ft.
400 Gallon sump.
The key at this scale, as well as smaller tanks, are light and CO2. Those had been the biggest challenges. We use 2 large mazzeii venturi valves for CO2 which have woked well. Due to issues in measurement, we ended up using a nice CO2 meter that measures partial pressure of CO2 dissolved in soluton, this is far more accurate than other methods and does not use KH/pH or any interferring parameters. CO2 was 45ppm, it was lowered to 38ppm for the time being. Beyond 45ppm, the discus turn darker and have signs of stress. The larger the fish, the more likely they will show signs of CO2 issue at higher levels.
Scaping is honestly very hard. I swim and float looking down from above, the owner hangs at style from the cross braces. I like 82F water personally vs a headache.
We lower the water to about 2ft or so. One one has an arm longer than about 2ft for work on aquariums.So this is one reason you rarely if ever seen deeper than 1 meter tanks that are fully planted all the way to the bottom, eve Amano's large tank is white gravel foreground(and I can personally see why, it was suggested here as well, but over ruled).
The tank gets about 1/3 cup of KNO3 per day, a few table spoons o KH2PO4, takes up an entire wall. The water change is simple to do and require virtually no effort: Turn a 2" PVC ball valve to drain to 60% water change in 15 min, turn another to fill in about 1 hour. You have to do large water changes simply to work on the tank without scuba. So large water changes provide some practical utility.
There's about 1 ton of driftwood in here, you can no longer see most of it.

Tom Barr

Not my tank, it's a client's of mine.
Yes, it's in a "living room" type place.
Takes up one wall.
The TV is a 50" screen but it's tiny compared to this.

That must take a lot of money to maintain (CO2, ferts, etc) but I saw your other thread and that guy is rich beyond reason!
I would absolutely love a tank that big, but when I think about it, it would take way too much time/money and work to maintain so I'm probably better off with my tiny 100gal!
My goodness, your sump is four times the size of my tank! Is it behind the wall in the room next door?
Do you get a lot of evaporation/dampness in the room - how do you deal with that if you do?
