I've been toying with a all in one nano tank. I've looked at the Biocubes and the Nuvo Fusions. I don't particularly care for the Biocubes solely because you have to get them with the PC lighting. I wish they had an option without lighting to save on the cost of upgrading to T5 or LED. I do how ever like how there are a TON of things you can do to them skimmer, pumps, lighting etc. The Nuvo Fusions I like because the can be ordered with LEDs and come in various sizes. I am very limited on space and thing this style of system may have a benefit to me. I was curious if anyone had and suggestions one over the other or a different system. I've seen the Redsea tanks they are beautiful but I cant justify spending that kind of money on a 40 gallon tank when if I had the room could set up a 90+ gallon for the same money or cheaper.
