I personally like T5 lighting right now, but I am also trying out MH. It's a bit of a toss up. T5 there is almost not heat consideration and coloration is nice and if you have individual reflectors (this is key) the light output fine for all types of corals. MH is HOT, but that glimmer is nice and this has been one of the best lighting solutions for a long time.
Thx tim...errr do u know the smallest light for nano tank ??
i guess i'll buy a new smaller tank...and how about the filtration for small tank ?? maybe i'll buy tank with 10"W
LOL yeah sorry. The links do have some larger lights. I used those to show the better (from what I can research) styles of lights. Any T5 lighting (with individual reflectors, this is a must) will do very nicely.
Is there a price range you have? That may help me narrow down a suggestion or two.
