Well since you said Radium I guess you already made up your mind.

However, for growth:

Only with a ton of actinic supplement.

He said growth, not beauty.

You can have both with the Ushio 20KK plus or the 14KK..

I use both and love both. Of course you'll get better growth with the 14KK

I've been interested in this one: http://reefbuilders.com/2010/11/22/aquastar-14500k-metal-halide-lamp-coming-coralvue/

6500K will smoke a ton of corals. The Ushio 14K is a good combo for growth and color.

+1. I was using Hamilton 14k on my flat and it was good. Love the color of my ushio 20 k+ at home. I think 14k better for growth though. That 6500 may get growth, but you will have a bunch of big brown corals

Hey Gresham can u get the plus bulbs in 400k....

 

[tuberider]

400k....

????

 

[eldiablosrt8]

400w lol don't write n talk

 

[tuberider]

Yes they do make a 400w, Bryan uses the 20K+ 400w.

 

[eldiablosrt8]

Ok gotta find them have found 250 not 400

There is/was an issue on the import of Radium bulbs that seems is going to halt import of those(at least temporary); luckily I'm set for 5+ years !!

 

[eldiablosrt8]

Well ordered bulbs 20k ushios. Thanks for the help

 

[seminolecpa]

RememberIi have the Ushio 20K plus not the standard 20K's.

 

[eldiablosrt8]

where do you get them from bryan

 

[GreshamH]

Aquatic Collection did a group buy a while ago. I bet Steve Ruddy @ Coral Reef EcoSystems up in Norcal could get them for you as well.
