Great article.. I was in the Boston area when the sun tube tank came about.. that was a cool idea. we used to trade sand and rubble when you came to a meeting to increase the diversity of our tanks. I mentioned that at my new club and well I got a few strange looks. if you were new and had a tank you got a free frag of something from someone in the club.. just for showing up. its how I got my first coral. its a different time that is for sure. but you made me smile remembering what we had at that time.
