I realize I'm a little late to the party, but the trip was a great time.
It was interesting having a look at all of the equipment and systems. All I have to say is that they gave me a lot of ideas I have neither the space nor money for.
I will echo Wayne in complimenting on how clean everything was. The facility is not normally open to the public and may have been spruced up a bit for us, but all of their set-ups were well planned and laid out and except for a bit of salt creep, the place was spotless. In fact, it was cleaner than probably 90% of the retail fish stores I've been in...
I can say that the Coral Reef has taken some major steps forward since Matt and Co. took it over and with it being just off of the highway there really is no reason to not stop if you're on your way through K'ville.
