Darwin,
The reef tank is worth the drive IMO. I'd call ahead if you are looking for anything specific. Also their hours are a little abnormal. Sometimes their stock is low, including live rock. Their prices are among the lowest in the area and the quality is among the best. They do not update their website from what I can see.
on the side, xrenx, don't go to Wally's, IMO, they always seem to have a brooklynella problem with their fish.
