Detane...you know I was thinking the same thing when I read the name of the thread but its only going to be a reef tank see, the title is just giving the name of who's reef tank it is... ie. DETANE'S REEF TANK as I would post HTORRES727'S REEF TANK. He's not stating that its going to be a tank to house a shark. However thumbs up on the bio ball if your'e going to do strictly reef (which the title of the thread self explains) and yeah get a skimmer either way
