Hi Sahin,
A couple of questions on this if you don't mind.
What did you not like about the KZ New Gen? How is the coloration different from the Coral + and ABS? Have you every seen the GE 6500 bulb everyone talks about? Is the KZ New Gen similar to that one? I tried the GE and found it to be too yellow.
And then on the Actinic bulb, if I used one in my 4-bulb unit, would I be sacrificing much PAR vs say the P+? What would be a good 4-bulb combo with the actinic? Like 14K or so.
Thanks!
I have the following white tubes:
ATI AquaBlueSpecial
ATI Coral Plus
Giessemann Lagoon Blue (despite its name, its a white tube like the ATI ABS)
GE 6500K
KZ NewGen -(looks like the Lagoon Blue to me)
Arcadia 14K - British brand
The KZ NewGen to me is like a standard white tube. Not too blue, not too yellow and doesnt pop the red/pinks like the Coral+ does. It looks too grey.
The Coral+ is the best ALL round white tube out there. Perfect amount of blue, green, yellow and a slight tinge of pink. It is the most balanced tube out there.
I like the ABS because despite most people saying it causes colour to wash out, if a couple of tubes are used in an 8 tube combo, it can be balanced out by using at least 5 blues or when Reefbrites are used.
The GE 6500K is a tube that can be used in an 8 tube combo with a fixture that has at least 2 LED clusters to drown out the yellow (ie you have enough Blue LED's to counter all that green/orange/yellow/red light).
I like this tube because it provides a very "full" spectrum and helps boost the yellow and red coral pigments which otherwise get lost in too much blue.
If you have a 4 tube fixture with two or more LED clusters, then go ahead and use the following combo:
Blue+
Coral+
--LED's-- (set RB=255, B=150 and W=105)@100%
Coral+
Actinic
With two or more clusters, dont be worried out PAR loss. You will hit the PAR levels with all that Royal Blue, Blue and White LED's.
So long as you are hitting 250+ PAR for most of your SPS, then that it good enough.
