dont wanna steal the thread but its pretty much the smae thing...how bout a 175 over a 40 breeder? I'm guessing the same? the 40 breeders are pretty low, but they're kinda wide (front to back) so would it be enough to cover it? i've got a 2x96 on there right now that i'd just use for actinics.

no the 40 isnt 40 ft...the standard 55's are 4 ft (48 inches) but this is only like 36 inches long..so 3 ft. still too long you guys think?
would i be better getting 2 smaller MH fixtures? if so...what wattages?

I stand corrected, i thought they were 4ft. Anyway the general thinking is 2ft/Mh bulb. Then again if the single bulb is two ft and the tank is 3ft you would only be lacking 6inches on each side. I dont see what that would hurt if you kept the corals under the lights. I got a couple Mh bulbs that I aint using PM me if you want to.

actinics arent completely nessesary...so says a lot of people on here anyways. They dont really give off usable light to corals i guess, but if you have the option to turn them on by themselves, then imo it makes a more natural affect for the corals, which imo = healthier corals.
You would turn them on a half hour to an hour before the other lights come on...leave them running all day while main lights are on, then once the main/daylights go out, you leave them on for another half hour to an hour. Gives sort of a monring/evening affect. But this is also why people say actinics have shorter lives...imo its not that the bulb life is short, its just that extra half hour/hour extra every morning and evening that just adds up after a while.
But they also add a really nice color to your tank (blue) so i love them...but no they're not needed really, but if you can eventually get them (doesnt really matter when)...then go for it

You should be fine with that diminsion. Just keep the light loving corals away from the edges.
Actinics..... well.... there is a lot of "are they needed". I personally have them. Depends on what rating your MH bulb is and what color you want your tank. I have 10K MH so I have actinic to add a hint of blue. If you had a 20K MH, it will give off a blue tint.
The higher the K, the bluer the light, the lower, the more yellow light. 10K being fairly "white".
