im thinking of getting 4 x 110 watt VHO's and 1 x 250w metal halide
i have a 66 gallon tank 48x18x18
is this sufficient for colourful acropora?
or should i get 2 MH?

i know 2 MH is good for sure but i dont want to get 2 if i dont really have to, this guy at this really small but awesome reef store was saying 4 vho and 1 MH is fine but i want some more opinions

thanks alot
