Lighting question

[scsi]

I recently purchased a 77G tank and plan on setting up a small reef. A few fish, some cleaners and soft corals in about 6 months after adding the live rock. Tank is 22 inches deep to the substate floor.

I'm thinking of the Aqualight Pro 150 (2 X 150 watt MH, 2 X 96 watt Actinic , and 3 x 1 watt lunar lamps) Do you think this will be suitable for this size tank or will I be limited to what I can keep in the tank?

btw... I'm not using the supplied legs for the lights. I have the unit resting on the top of the tank which is fine I hear, as long as you keep the underside cleaned often.
