I suspect the 400w Iwasaki would blow away those numbers. The intesity of those bulbs is high!!

Ok,
So on my tank currently I have 250w Iwasaki.
If I change my bulbs to 250w 10000k bulbs the par would be less?

Judging by the output of the 175w 10k bulb I would have to guess that the 250w versions output should be fairly high. But the Iwasaki would probably still be more?

yes, if you are changing from 250 Iwasaki to 250 10000K, you are mostly doing so for looks.. the 10000K will still grow your corals so don't think that your growth will stop if you drop a little par. this also depends on what ballast you are driving your bulbs with.. if you use a MH ballast to drive the Iwasaki the PAR will be a little lower and if you use a M80 ballast to drive german 10000K the PAR will be higher.. so it could end up being that there would be a very minamal change in PAR after the fact

Just an FYI. Darren ran 65k bulbs, tried 10k and loved it. A guy I know locally tried the same thing and hated it. His 10k is over my tank now. I think it's all a matter of what you like to look at. If you saw the growth I get with 10k, you'd be amazed. I wouldn't want any faster growth!!!

You always hear so many diffrent opinions.
"Iwasaki best growth......10k good color"

I do like the color of my Iwasaki's with 4 t8 actinics OD 2X.
but I do like the color of 10k bulbs as well.

I suppose another example of a great 10k lit tank is MTDEW man's on RC.
2 10k bulbs, one single ended and one double ended and awsome growth and color on his tank.

How often do you replace your bulbs?

Wow those numbers are shocking! That tank is definately not that blue.. My tank is not even that blue.

"The only way you are going to get a nice pic though, is to redo the heck out of it with a photo program or set the white ballance to cancle out the blue and show the true colors as I did on the pics of One_Divided's tank."

Steve, I have a colour adjustment setting on my camera. I just take the blue down 2 notches and it looks identicle to the way the tank looks. I personally like that look the best.. I got some pics of brad's tank with the true colour. I'll post one later..

Theoretically, every 12 months. However, I never get that far. And now with Radiums, it looks like probably after 7-9 months on these ballasts!!

I am going to have to look and se if I have something like that also.. probably do just haven't found it.. can you find the actual name of the function for me Adam, the only problem I see is that you will also be decreasing the level of blue for stuf that is suposed to be blue.. but it might be so small it won't matter so hey.. might be the way to go..
