    Hi Guys

    Im busy building light fitting that will house 3x 150w MH & 4x 28w T5's.
    My tank depth is 800mm and im planning to suspend this fitting 300mm
    above my tank.

    My questions...

    1. Will this be sufficient to keep most corals?
    2. Will i need a chiller or will 4 120x120mm fans inbetween my MH's blowing down be okay?

    Thanks in advance!!!!

    if you keep the tank open on top then that helps a lot. Fans can do the trick. The problem comes when you have a closed hood

    I do not know what the climate is like at Retreat, but in Zululand you will need a chiller for sure. If you do not have this violent humidity we have the evaporation might help to keep the temp down. I think you will need a chiller though.
