When I was in high school (over 15 yrs ago) I worked at PJ's pets and they were the only store in Edmonton that had saltwater anything. I remember hooking up the spraybar over the giant bin of bio-balls and thought this is the best filter ever!! I believe the LR was by special order only and you had to pay first.
I think one of the biggest improvements has been transportation of livestock. We were lucky to get damsels or a few tangs on the order sheet it was usually 1/2 page.
