What bulbs should I buy need help
 

I have a 72" costa life fixture with 3x250watt metal halides with 14kpheonix bulbs and I need to replace my 4x96watt power compact they are violet wich should I keep the violets or should I use blue bulbs but don't know wich spectrum to choose I am ordering from marine depot any help is appreciated thanks

I would say that PC are for before and after the MH's so do you like a blue effect?

I would say 2 x 10k and 2 x 420 Have you read the reviews on Marine Depot for these bulbs?

Yes I have everyone really likes them but I'm willing to buy from anywhere as long as they are good and also I was thinking of buying them all blue I kinda don't like the violets much

You can also call Custom Aquatics there are in San Diego and speak with the owner just like Marine Depot knows a lot about the PC bulbs maybe he can be of more help. I have used the 50/50 and actinic worked great for me.

Just don't know wich are the most blue I'm thinking 420 are all blue right

Will do tommorow thanks for the help

You have the MH's as your mainn light source. So for the PC's I'd look for a dramatic dawn to susk effect more so than the daylight color. I would personlay bo with something very blue or even atinic.

Personally I have liked the look from 460nm blue PC bulbs more than 420nm. I find that the 460nm blue shows off the corals better.

You could always get from Marine Depot a Dual Blue (460/420) which is one tube bright royal blue and one tube an actinic soft purple.

I was looking at my Marine Depot magazine and like grigsy stated, I second his recommendation I do not think you will like the 420 they are more violet,

Those are the ones I have now so I'm waiting on the 460nm thanks for the help

Thanks going with 460n
