i have a couple of these and like them but as far as plug and plays go they all have their own attributes/problems but are still nice little systems. and although i like the look of all of the dif "nanocubes" (oceanic, jbj, redsea, aqupod) i truely believe that they are just beginner tanks and most people in the long run wish they had gone with a regular glass tank and bought all their own components to match the theme they are aiming for.
these tanks are limited by design and can only house certain critters. they have inherent problems like poor lighting, poor flow, lack of surface skimming, and over heating and people generally end up modding them to meet their needs. they have a place in the aquarium hobby, but are def not the only option.
setting up a tank yourself will teach you a lot more about what is truely needed in a reef tank and will allow you to spend your money on those things - lights, flow, skimmer ect. and you can match your components to the theme you are choosing to build
- ie their are two ways to approach a reef
for example you could be:
1) the plug/play version and ask "OK i have an aquapod, what can i put in it"
or
2) the theme tank version and ask " OK i want to keep a pair of clowns, some zoas and a clam what size tank and type of equipment do i need"
i would prefer to be in the second group myself...........
