4x2x2 tank. The kit comes with hanging brackets for the Kessil units. You can always add more later.I saw this literally an hour ago on BRS how big is your tank? I think this is a great bundle. I dont know if i should adda third kessil or not.
Im also torn between doing the reefbrites or blades. the blades come out to more money i believe. they have that coral glow one which is more purple.
