Yep, Phoenix bulbs -I love them! I am going to order one for my other tank downstairs

I will be needing to replace the Phoenix bulb on the 33g cube tank, and am considering other brand bulbs. Any suggestions? I really like the level of blue put out by this bulb ... very nice. And I believe this bulb puts out pretty good PAR, which is always awesome

I am almost afraid to try another bulb for the fear of not liking the way it looks. Because bulbs are not cheap, and I am a college kid

I was considering using a 10k for 6-8 months on this tank to really ramp up the growth, and then after that rotate in a 14k, or a 20k.
