I have an 8x54 T5HO light on my tank and I really really like it, it gives great lighting, the only thing is, i see tanks with T5s and they give off more of a blue color overall and mine gives off pretty much a complete white color, the only way to get the blue color i like is to turn off the white bulbs, is there any combination that will give off the color im looking for, or am i just being to picky?
