Lighting for a 60g Reef?
 

If i were to get a 60g Reef tank would a 400w halide light cut it???

I can't see why not if you divide 400 w into 60 your going to have a fair bit of wattage per galon like around6.5-7 watts per gallon nothing wrong with that. I had 2x250's over my 65 gal and the corals loved it.. ny next tank im going to have 400 w over my cube tank 30x30x30

Ok... well i don't know how big it is sooo... thats because it's my brothers and i haven't asked to see it.

What are the dimensions of the tank?

I will be using a 400w over my 65g (36" long), but I will be using the Lumenarc II reflector which spreads the light waaaaay better than other reflectors.
