will this help me?

[zangler]

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.

I wouldnt use anything lower then a 6500k bulb

[zangler]

why?

I think that shag26272 may have been confused when you typed 4200K, I think you typed an extra "0" in there. Is it a blueish light? If so, you did type an extra "0". IF the buib is truely 4200K it will be way yellow, you most likely wouldn't like it.

[shag26272]

HuH? did you mean he meant to put 42000k?


i think its some kind of freshwater NO bulb probabally

[Toddrtrex]

I was thinking that he meant a 420nm bulb. Actinic if you will.

[shag26272]

ahh ok

[Toddrtrex]

I really should post so darn late ;)

[zangler]

no...it is yellow...but with the 460nm actinic it does not look bad...i just want to know what i should do with it

[zangler]

it is a freshwater NO bulb

I cant remember correctly maybe someone else can answer but could this bulb produce unwanted algae for him?
