Best Bulb Combo?

[mattdean]

When I had a 4 bulb, I ran 2 blues (22K) 1 KZ Fiji Purple and 1 Dua White (17K). It was very nice and colors popped.

Here;s a pic- with a crappy camera- under those lights of the old tank :

I should mention, everything grew like weeds under those lights as well.

do the purple and blues promote growth at all or just help make colours "pop"

[mattdean]

The different spectrums contribute, however, the white is more for growth than anything. If I could, I would run just blues and purple.

If you get a Blue PLUS, I believe that has more growth properties as the "plus", in my understanding, is an added "white".

yah im looking at some ATI specials and blue plus now

I am running ati blue plus for atinics and they are awesome!!! alot more blue than the giessman

[chris88]

the plus is not added white in the ati blue plus, it just means it has a wider blue spectrum then an actinic. corals use blue, red, blue green, orange, to photosynthesize with, they do not use green light. Yes you will get good growth from blue bulbs just like you will get good great from a 20,000k mh bulb which is all blue. But i would run a wider spectrum such as the folowing.

Ati blue plus or kz superblue
kz fiji purple
kz new gen or ati aqua blue
Ati blue plus or kz superblue

this will give you good growth and a nice color.
