I have 150 gallon tank. Currently I use both compact flourescent and VHO lighting. On the VHO side I have space for 3 bulbs. I am not sure what the proper mix would be. In the tank I do have leathers, derosa clams, hammers, brain and mushroom corals. What would you reccommend those 3 bulbs should be? The compacts are a mix of blue and white. thanks...

Well, depending on what livestock you have and plan to keep in the furture, I would consider metal halides and ditch the CF's. VHO would be you actinic and MH's would be good for just about anything you keep. How tall is the tank?? I wonder if you are penetrating the depth with the lights you have?!?

Now if you are talking about adding three VHO's, then I would ask what bulbs you are currently running. Wattage and kelvin values please.

The wattage i think are 40 watts each. Not sure on the Kelvin.
