[jubjub]

i think i decided down to xm 10k's or ushio's 10k.... trying to get some good grow out on my tank what would you recommend?

trying to get good growth, but not have my tank look totally yellow

If you're going with SE bulbs powered by a regular magnetic ballast, go with the Ushios. If overdriving the bulbs with an HQI ballast, DEFINITELY go with the XMs. XM does give better growth overall than any bulb I've ever used though.

I've had very good luck with Ushio 10k HQIs. Good color and growth. But I have never tried XMs.

vader^^^ imma be running DE bulbs with electronic ballasts, although they are the stock oddyssea ballasts at the moment so, more like underdriving lol...

think imma try the XM's i got plenty of corals i just need the grow out.. ha hopefully be like the corals on steriods lol

Ushio's 10K will have the best grow rate by far, but the xm 15k or 20k will show better colors.

I had Ushio DE 250W before and it was pretty darn yellow. Never tried the XM

I have one now combined with 2 VHO actinics which helps with the yellow, but the growth rate is strong.

The 10K Ushio's look great combined with Super Actinics.
I am using 3 250W 10Ks on a 210.
