Not sure what exactly you're looking for here but fyi I've been running a Biocube 14 (I think 14?) for like...two years? And I've had no issues what so ever. My only complaint is that it's been kind of a booger finding replacement bulbs and one of my moonlight LEDS has burned out...which doesnt seem right but oh well.
Well, there seems to be a decent price difference between the Biocube and the others so I was wondering if there was a significant difference in the quality.
