Advice on adding T5 lighting...

[TRPlacek]

I'm considering this kit mainly because I have limited space. I would only get one kit and put one bulb on each side. So what two bulbs would you recommend if I go this way?

I have this kit set up just like you are talking about with 1 t5 in front and 1 in back of my gen 2 pros. I went with blue+ on both mainly because they sit so close to the water line that two different colors didn't blend well. They have definitely aided in the growth and color of my coral. I originally bought 2 kits and would have loved to be able to fit all 4 t5s to add more spectrum but I too have limited space and was unable to make all 4 fit well.
