Naser:

Do you have any supplementation for the 10K UShio?? Do you have pics?? I am debating between the 250W Radium or the Ushio right now, thanx.

Andrew,
I have 250 10K Ushio's on both of my tanks.Stop by and see it in person,will ya I have VHO actinics for supplimentation.I like those bulbs alot.
This is a shot of my 75gal.

oops,wrong pic
This is very old pic,about a 2 yrs ago,but lights are still the same.

im doing the same.. using two 95 watt vho atinics with my haldies...

[MtnDewMan]

I prefer the Aqualine bulbs. I used two 250W AB 10000k bulbs powered off a PFO Dual HQI ballast supplemented with three 110W VHO actinics.

i was shooting for more mogul standard bulbs.. about to replace mine and wondered if anyone tried coralifes or hamilton?

[MtnDewMan]

The 10000k AB bulb is a mogul based bulb. Yes, I fire it off an HQI ballast.

Thanx, guys, still am wondering if I shuold go with two 250W Radium with 4X 55W 10K PC or two Ushio and actinics. Mmmm.... The Ushio with actinics looked blue, me like it.



MtnDewMan, didn't you post a pic of this 250W Radium you got?? It looked really blue in the pic, did you have actinics on at that time?? Are you using that bulb or you gave up??

[MtnDewMan]

Yes I did experiment with at 20k 250W bulb, but did not give it a chance at all to break in for 100 hours. I basically gave up on it right away as I didn't want to mess with a good thing I had going already with my current lighting.

Here is the link to that thread comparing the pictures I took ...

10k vs. 20k Experiment (Pics)

good lord thats blue....... i though ab's were only double ended.... sorry. are they alot brighter with the hqi?

[MtnDewMan]

The 10000k bulb on HQI is more intense yes. I have tried the HQI ballast as well as the standard ballast and definately get better results using the HQI ballast, both coloration and growth.

And yes, that Radium was very very blue ... but probably would whiten up after a breakin period.

[kevinpo]

The Radiums take about 8 days to turn whiter. IMO they look a bit dim compared to a 10,000K bulb on a HQI ballast. My favorite look so far is a 10,000K and 20,000K mounted side by side. The color blends nicely.

Kevinpo:

What do you think if I use the 250W Radium with 4 55W 10K PC over a 120G SPS tank??? Any input on this combo???

[naser]

one raduim monti?

[montepora]

Naser:

Nop, I am going to have two radiums with 4X 55W 10K PCs, what do you think??

[naser]

whats the lenght?

[montepora]

Naser:

I have a 120G tank, so the length is 4 ft. Since I have DSB, the depth is abuot 16".

[naser]

see my 120 is 6 feet.... thats what thru me off. i tried two 400's on a 6 foot tank and no way did it cover it.. four feet would be nice.. you should go with vho's though.. i think youd be happier with the different colors. like aquasun, 50/50 and atinic... you have more room to change. lets say two radiums. blue right. well then you add a aquasun and a 50/50? the combos are almost endless...
