The coral tank was bad on many levels. Bad coral selection, bad coral placement, overstocked with some really bad choices for fish, and NO flow in the tank.. they show the wife pulling a linckia starfish out of the water and holding it out under the lights. Worst thing you can do to one of the most delicate starfish out there. The refugium they built is no way sufficient to filter that size tank and that many fish. From what was shown, I would give a 100% coral death rate and at least a 75% death rate on the fish in the first 6 months. Size of the tank, being so tall, makes it very difficult to do any work on the tank, which is really bad on a reef tank because your always getting your hands wet moving corals around.
The kids tank was cool, only issue I had with that one was again, severely overstocked with inadequate filtration.
