I have at leats 3 more this size and larger to do yet.
This one is a personal client's.
It's in their Den, not much else is in there except a nice view of a number of famous Hollywood stars, LA skyline, the San Gaberial mts, the ocean etc

The home is not yet finished. He is a possessed fish hobbyists by all accounts.
See the fish list, Amano does not do fish list like that.
High profile Beverly hills etc.
The other 3 will be for the LA Zoo's Amazon exhibit.
They will be in the 20x6 x 4 foot range.
One community like this one, one Hydrocoylus/stringrays etc, one piranha.
That does not include the other folks that will see this in the client market base I deal with.
Likely will get several more out of this one.
The tank will grow and evolve nicely.
The wood weighed 300lbs for one piece alone. See pic, the 2" PVC pie is a just in case it moves type of thing.
Took 5 people to set it in.
Fortunately, nothing moved afterwards and filling.
Placement ballast rocks will be removed after the wood soaks a bit more.
I am going to do some replanting in 2 weeks.
Then polishing around Oct 5th for 3 days.
4 gaint 1 micro bag filters, 500wUV, pure O2 controller injection system to maitain at least 8ppm O2.
160lb petrified wood pieces.
Tank is 30 minute old in the pic.

Ferts are EI, the client doses and likes to feed the fish.
700Gallon RO reservior and 1000gpd RO unit.
Cleaning and maintaining are secrets

Maybe I'll tell later.
It's not hard really.
I expect minus feeding fish, to have the client spend 2 hours a week of work.
He has 20+ tanks now and spends too much time that takes away from his family, so one big uber tank is here to prevent that.
The water change is auto valves, nothing more than a turning a lever and fill/drain rapidly.
All my client's tanks have this added for the last several years.
There are a few stem plants, but they only need trimmed once every 2 weeks or so, and while the tank drains, the water levels is low and you prune with long tweezers and scissors.
By the time the water levels come back up, you get out, add the ferts, clean filters etc as needed(bag filters are the only things that need changed really and the prefilters which are quick).
I maintain other 4ft deep tanks with less access than this tank.
There are some simple tricks.
