Building proces of my 21 feet long concrete aquarium

It's coming together nicely. I like your concept of bonnethead sharks as the main species with some schooling dithers. Less is definitely more here.

The tank dimensions are odd, was this due to house plan constraints? Hopefully you aren't wishing the tank should be bigger....

Very interested in your filtration if you could elaborate. Will you have a quarrantine area or sizeable hospital tank too?

House plans constraints were nearly none.
Groundfloor may only be 55ft in depth, first floor 40ft.
Aquarium size was determined first, then afterwards the house around it.
I'm happy as it is. Also happy to go with glass instead of acrylic.

Yes ofcoarse I need quarantaine tanks. What you do when a big fish is getting sick?
I'll build a 3000L (800 gallon) and 15000L (4000 gallon) quarantaine tank.
I won't keep any fish before QT tanks are ready.
