lighting 70 gallon

[phillybean]

I dunno if I want to help because I'm so jealous of the deal you got on that tank...

But I will anyway

Im running two 250 watt 14k with two Sunlight Supply T5's with stock bulbs and Im getting great color and growth. I plan on replacing the 14k with XM 10k for more growth and changing the T5 bulbs to a Pure Actinic/Actinic + combo. The key is getting good par and great color.

I think either set up will treat you right, depending on reflectors and bulb choice. A fail in either area will cost you par.
