Lighting for a 37 Gallon Tank

[Reddobie]

I have a 37 gallon tank, 36"x15"x15". I have 2 PC 55 watts ( 03 Actinic and 10,000K) lights on it now. I would like to have SPS coral and add a 175MH(10,000K). Should I keep the 2 PC 55watts, as 03 Actinic(2) or add 2 more for a total of 4 PC 55 watts, 03 Actinic?

I think you are gonna be just fine with the 2 PC's and a 175 watt metal halide. However, the other options you mention would be nice, but not really necessary if you are on a budget.

The 36" parallel reflector made by PFO will accomodate 1 or 2 MH and 2 PC (or linear flourescent). It has mogul sockets (won't hold double-ended MH). There is a 24" parallel reflector also that only hold 1 MH lamp. http://www.pfolighting.com/aqwebsite/aqretrosocketsreflectors.htm
