New light combo suggestions?

I have an aquaticlife light that has 4 54watt T5 lights

Its light changing time, and Im thinking of getting away from the stock bulb arrangement currently I have 2 10k white and 2 actinic blue plus

Id like a bluer look to the tank, but want something that will promote growth, I have mainly softies with few lps

I saw a thread here a while ago that showed tanks with different bulb arrangements and Full tanks shots but cant seem to find it now

 

Try 2 ATI Blue Plus, 1 ATI Purple Plus and 1 ATI Aquablue.
Place the bulbs front to back
Blue Plus
Purple Plus
Aquablue Special
Blue Plus

This will give the bluest look, switch the Purple and Aquablue if you want it to look a little lighter.

 

I was thinking almost the same thing, I dont really understand the whole par thing, will this give good growth as well?

also where do you suggest getting the aquablue special? I cant seem to find

 

This the combo I use right now and there is great growth under it my lights are a little small for my tank so im upgrading but you can find Aquablue special bulbs at bulk reef supply.
