20g lighting?

[NANOFOOL]

im starting a 20g and i have a 175 watt 20k bulb and was wondering if i should have other lights to accompany it, i was thinking about some small t-5s or pc bulbs. what do you guys think?

 

[GSMguy]

no need that will be plenty of light for your corals

 

[NANOFOOL]

it will probably be sps dominate

Why would you want to accompany a 20k bulb? Like GSM said, it's enough watts and plenty blue. Do you have a good reflector?

Nanofool-

I think that your fine for lighting...your sps will certainly grow well under a 175w mh....no question in my mind...

If you want to alter the color temp by adding some t5's....or simply up the intensity a tad...thats your preference ... at this point its more preference than necesity
