Great tank wishing for similar results when finished with the construction of my 4X3X30" setup is complete. Gives me great inspiration after a hiatus of 11 years to the hobby.
I HATE my LED's. I have the Pac Suns with white/blue LED's and I can't stand the colour. I don't think I will ever use LED's over T5 unless there are some significant improvements. I have yet to try the newer LED's with a more diverse colour spectrum so I can't comment on them.
Right now they are good for electricity usage...that's about it.
