well I had an extra older blue+. So I put it in so that 1,3,4, and 6 were all blue+'s. And as expected I get the windex look...but that's not terrible. I tried just the fiji purple and an old aquablue in 2 and 5 respectively...crap. The aquablue is WHITE and washed everything out...i was amazed AND reminded of why I stopped using it.

So then all I had left was the fiji purple and two super actinics. The actinics alone did almost nothing...except give a purple dawn dusk. (very purple) But add in the fiji purple (which I'm guessung the purple+ will look like) to either slot and boom it's white again. So I'm guessing that the purple plus is more of a brightener and less of a purple addition? And thus I'm thinking that all blue+ with just one purple+ will probably do the trick for a 20K look? Does the purple+ boost par at all, or is it weak? And finally, where would/should I put the purple+ (dawn/dusk, or in one of the other 4)?
thanks again.
