Question on Actinics

[kdeyarmin]

I have a Coralife Aqualight Pro. 3 - 250w metal halides and 4 actinic compact flourescents. The CF's have a purple hue to them. I would like a more bluer look. What type of bulbs should I replace the 96w CF's with (420, 460, ect..?).
Any suggestions would be appreciated.
Thanks,

I like the look from 460 nm blue compact fluorescents. I use those in my 24 gallon nano tank. They tend to give a little more brightness to the tank and also a little nicer color.

My frogspawn looks nicer under the 460 nm blue where as it looks more blan in color, almost brown, under the 420 nm bulbs. Doesnt stand out as much.

I have a mix of compact flurorescents. My bulbs are 420/460. To me it covers a nice spectrum. But if you want less purple then 460 is the way to go.
