T5 lighting question

[burtonpj48]

I have heard about how popular the fiji purple bulbs are. Are there any negative impact on the coralls, since the bulbs are not a true blue light? What im noticing from my tank now its too much white light. I have also read how the fiji purple bulbs will make the collors stand out more. Its something im considering to add more of a vibrant color in my tank.

Nope. Perfectly safe. High PAR values too. You can't go wrong with this bulb!

Actually, there has been some published research that shows lights with a large amount of red spectrum inhibit zooxanthellae reproduction rates: http://www.advancedaquarist.com/2009...earchterm=None

With that said, I still use one Fiji Purple knowing this is likely a negative consequence because I like what the color does for red and purple coloration.
