Help me decide which ballast and bulb combination, PLEASE!

[84chris]

Its for my new cube which is 36x36x13. I have two m57 ballasts one is a 250 and the other is a 400. Right now i have a 14k generic bulb which looks more like a 10k. It is a mixed reef with some pretty decent sized sps. Everything is growing great but i need more color and i dont want to add supplement lighting. So my question is do i go with a Radium 20k 400 watt bulb or should i stick with the 250 watt ballast and run a 14k bulb. (which i need suggestions). And like i said they will be run by m57 raw ballasts. Thanks

Ive heard great things about the 400w Reflux 12k.

How blue is it? Like i said i dont want to add supplement lighting.

There are guys running these with no actinics at all

Reeflux 12k 400w run pretty blue. Certainly no need for supplementation IMO.They also give off a decent PAR unlike the 250w. I recently changed to marine-lux but would certainly consider the Reeflux again. I like them.

250 watt 14k pheonix with Lumenarc stealth's

They are being driven off Icecap ballast, but I have seen the pheonix's on magnetic ballast and they are a bit whiter.

Need more opinions please!

If your not looking for tons of PAR,the 250w XM 15K has a great look.
