OK , I was told that I would need about 8 watts of light per gallon for corals depending on what kind. I am still confused about this wattage thing. I understand the metal halide wattage but when I start looking at PC's, am I suppose to look at their wattage use or their wattage output? Also, if I get a double bulb or quad setup is each length cumulative or is it still the same as one bulb.
Example being.......
1x96W Actinic 03/10000K (50/50) 4-Tube (Quad)
What do I have here as far as final output towards requirements? Do I have 4x96=384 watts total, half being in the 10k spectrum and half being in the actinic 03 wich would almost be enough for my 46 gallon tank, Or, do I only have 96 watts of lighting in the tank?Sorry to keep hassling about lights. Thanks for the help.
