I've had my biocube for about 5 months....I understand what you mean by feeling limited, especially after previously having a 120. As a matter of fact just the other day I was pondering and checking the bank account to see how soon it would be before I could purchase a large cube tank....looks like it will be quite a while! Til then my thousand dollar biocube will have to do! By the way I'm still looking for another 12 watt blue and white panorama fixture to finish out the hood...how's yours doing.
