A friend of mine used to have an aquarium maintenance business. He had several accounts that had to be cleaned this way, and according to him it looks like a lot more fun than it actually is. (Of course being bitten by moray eels and stung by lionfish, which has happened to him, did not sound like too much fun to me...) Still, I have always been very impressed by the huge tanks at Seaworld and Disney, and the pics in the OP look pretty impressive, especially with the diver for scale.
I even have duckweed in my water bong!
