Thanks for everyones input, much more than I expected to get!

I think I am going to order one Iwasaki bulb and give it a try on my 58gallon first. See how I like it with the actinics. It may be awhile before I can get the 75 setup as I will need to get rid of the livestock and will need to find a bigger skimmer for it as I only have an Aqua C Remora on the 58.

Thanks again!

Chris
