6500k Iwasaki Bulb to tone down

acropora_nut · 05/02/2008, 10:18 AM

Hi Guys

Have a quick question for you ,I'm going to be running 2x 400w 6500k Iwasaki Bulb on my new sps system .Tank size 55" 32" 24"

I used to run 250w reeflux bulbs 10000k on my old sps but fancy a change so opted for the 400w 6500k Iwasaki Bulb .
Now we all know to well the orange,yellow look I'm going to get form the 6500ks so i would like to tone it down with some blue T5 narvas.
What sort of wattage do you think i will need to bring back the look towards the 10000k area.

If you think the Navas are not the T5 bulb needed what T5 would you say go for .

Forgot to say that I'm running coral view 400w ballasts with 2x large lumenarc reflectors

Thanks guys

yours

Not sure about the 400 watt, but I ran 250 watt single ended Iwasaki 6500's on my tank and in my opinion, there is nothing that would have made it a 10k look. VERY yellow.

I was thinking of adding 3x 54w T5 Narva blue tubes ,what change in cosmetic look would you expect .

try using the specific "eye ballast" for those bulbs.. I Heard the eye ballast makes the 65k iwasakis burn whiter and brighter.
