the cpr nanocube is a new product for 2005. it comes in 3 different flavors: bare cube, w/ or without canopy; cube with 2x13w pc jalli light fixture; and cube with black canopy with custom sealife 1x9w + 1x27w pc sealight kit installed.
I own the version with the canopy and sealight installed. the measurements are 13.5 x 11 x 11.5 inches. the total volume is almost 6 gallons not including the sump. there is an overflow and sump which has biobale in it.
compared to the cpr nanocube, the jbj looks cheap and tacky. the cpr cube looks very elegant, especially if you get the canopy. the only downsides are: 1) the overflow can easily suck down a small fish or shrimp. 2) the rio pump that comes with it is LOUD (subjective). 3) it is really expensive, compared to the jbj nanocube. I bought the cpr cube at cost, and even then it costs more than double the price of the standard jbj cube.
overall, I lreally like the cpr cube. I imagine the high price (close to $300 for the top of the line model) will keep most people away, but I've been spoiled by its clean looks. I plan on adding another 9w actinic to bring the total up to 45w.
