Although not all reef tanks, they are all large tanks. I was not sure where to post this so i thought here would be ok, sorry if i am wrong. The Large reef tanks at the Vancouver Aquarium were too difficult to take pictures of as the room was fairly dark and there was a flash on the tank when taken. When i finally figured out how to reduce the flash the colours were not great so i did not bother posting those pics. However there are some other reef tanks, the one with the large clam is probably around 12-1500+ gal.
There are lots of pics:
