JB1974:

I was thinking of using a 250 Iwasaki in the middle, but Stephan felt it would take away from the beauty of the Radiums and yellow the color.

However, I like your idea of using the Iwasaki's for part of the shift. During the day when not home who cares what the tank looks like.

What is your opinion on starting off with 10 hours a day and adding 15 - 30 minutes per month. I wonder if one could push the bulb to the 12 month mark by finishing off the life of the bulb at ~14 hours a day.

BTW are you supplmenting with any VHO lighting.
