    Will 1 250W bulb be enough?

    I have a 33gal. tank. 36" L x 12" W x 18" H and was thinking of going to 250W MH. Will 1 bulb over a tank this long be enough? My concern is will there be enough light on the sides of the tank. I know the middle will be ok.

    Thanks!

    I think you'll be ok.

    Ideally, MH's should be spaced apart every 2 feet as that is the best case scenario.

    In your case, what you could do is have the more light demanding corals placed in the middle of the tank, right under the MH and have softies and LPS and such placed at the ends of the tank....

    You could even get away with a 175w, as your tank is not very deep.

    Hope that helps.

    agreed! i have a 60 gal. 4 X1X2' high. had a 175w lamp, just barely enough light for sps up high in the middle, went to 250W, now my sps are doing fine, have softies at the bottom and sides and 5 or 6 sps mid to hi level directly under the lamp. works great. Have to watch the heat though. May end up installing a fan. With 30 gal., u'lll probable need a fan.

    Yup, Gerry's right...

    You have to consider the heat issue. Will this be a pendant or a bulb within a hood?
