For what they cost and what you get, and for as many problems that has been associated with them I still am of the belief a nice 30 gal oceanic cube or smaller, along with an AC110 hob filter, a MJ600 powerhead and a CSS65 skimmer and Coralife quad 96 watt light is as good a deal or better than any aqua pod or nano cube can ever dream of being. At least leaks and cracks are not an issue, neither is cooling for the most part, more capacit in about the same space a a 24 gal cube and a heap more peace of ind. My run a few bucks more overall but if you knock off the price of a skimmer its in the same price range, and even then neither of the self contained units have a darn skimmer either and fitting one to them is a chore if not almost impossible.
