20k radiums, any opinions?
 

I am thinking about putting a 400 watt radium over the tank (75G) has anyone had experiences with this bulb? Another thought I had was to supplement with some 6500k OD t8s so it is not soo blue. Any opinions are more than welcome.
Thanks and have a great night everyone,

Kelly, if you do a search here and RC, you'll find enough opinions on Radiums and ballasts to run them to keep you reading all summer!!

Hey Kelly,
On the new 230 I plan on having 2 400w radiums and 2 250w Iwasaki's, this is on a 6 foot tank. I put them on in combination in my 90g recently and the color is gorgeous.

Brad is right, you can read forever on "Radiums".

cheers

Right on, Thanks for the input guys.

I recently added a radium on a 430 watt son agro ballast to my 75 gallon. I really like the light. It is a nice bluish/white, but not as bright as a 400 watt 10k or Iwasaki bulb.

As mentioned there is a lot of discussion on this board about the subject, so I won't bother with more details.

I have purchased a new 150 gallon to be set up in July/August and will probably go with two radiums and a 10k. I really like the color of the radium, but I would think that can be somewhat subjective as some still find it too blue. I certainly don't.
