T5 lighting question
 

Hello everyone! I am considering changing all my bulbs. I currently have the 4 foot current usa 54w 6 bulb nova extreme system. I have been using the stock lights for about a year now. 3 460 nm actinics and 3 10k. I have a few soft corrals and also an lps. The tank is a 90 gallon, 24 inches tall. What would be a good reccomendation for spectrum of lights, in a system like this.
Thanks.

My opinion is aquascience......best par of all the bulbs.....2 or 3 blues then a mix of the 15000k and the duos.....:wink:

What are you basing the claim that they produce higher PAR on? I'll be replacing my lamps within the next month and have been humming and hawing about Aquascience but aside from their BS advertisement disguised as a "study" I haven't found much to convince me to change to them. To date I've been most happy with ATI lamps over the Giesemann and Aquascience I have used in the past. I'll probably stick with one KZ Fiji Purple regardless of what I do though.

here are some par comparisons for T5's

Make sure to get a fiji purple for sure

I'm using:

2 x ati aquablue
2 x ati blue+
1 fiji purple
1 uvl super actinic

love it!!

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!

Yeah that's the "BS advertisement disguised as a 'study' " to which I was referring above.

If you look at the link provided by Canuckgod420 above: http://sites.google.com/site/tfivetesting/par you'll see the PAR values are no better than ATI lamps.
