I've been researching as much as I can for the last year or so on giant concrete aquariums. I've met with several concrete guys and so on and so forth. The thing I keep getting hung up on, is where the heck do you find giant size equipment? As for as the containers for the sumps, that's a non issue, but where the heck do you find the giant skimmers, chillers, reactors etc. I am planning to be around 2200g in the display tank. Any insight is appreciated!
