i have a 40gal tank i just set up and have a 65w PC with a 10,000k and an acentic...i still have the crappy 15w 4200k light that came with the tank, and both hoods will fit over the tank...should i use it? it does make things 'brighter' in there...but not sure if it will help my tank at all (or even hurt things?) i plan on fish and some coral...actually not sure what kind of corals i could do (advise please). thanks in advance.
or...should i replace the 4200 with another bulb? it can take up to a 19w bulb....thanks.
