I have the JBJ nano cube. There are upgrades available,a dn sunpod makes a 20 in. MH system that fits across it perfectly. I just posted my first pictures on this site. REEFER545 is the name look under fish photography. I still have stock lighting, and the only problem I have run into is not enough flow and temperature in the summer. I just bought a chiller and I added a 106 gph powerhead in the opposite side of the tank set to turn on and off every fifteen minutes. They are great and easy to take care of. Only other probl;em is that my arm does not fit inside the filter compartments, adn if somethings falls inthere my fiance has to get it.
If I could do it over again (i will once I move) I would definately buy a much larger tank.
