How to acclimate tank to new light?
 

Well so I got my 4 bulbs fixture today and will be getting ATI bulbs for that (blue+, blue+, purple+ and coral+).

1. Should I get two blue+ or one blue+ and one true actinic? Which one will have more coloration and all the good stuffs like growth?
2. How should I acclimate my tank to the new light?

My previous light was 30" dual T5HO. Should I start running it without any acclimation?

Suggestions please :)
