I guess its all just a matter of preference but I really enjoy the shimmer effect I get with my halide. Although I wouldnt mind having some t5 actinic supplementation.
I was not trying to debate your opinion, which you certainly have the right to, I think we can agree to disagree that MH is overkill for Nanos. Why do I disagree? Because you can get closer to the 10wpg mark with halides than you can with t5's on a 30g tank.I didn't say it wasn't possible. I said it wasn't necessary (Overkill is the word I used). Are you debating that?
