I run 6 hours in the summer months to keep my electric costs down. 8 hours during the other months of the year.

When I had radiums I ran them for 6 hours a day. Best results for me.

6 hours in summer, 9 to 10 in winter. And something in between for spring and fall

Are you guys running other lights with the radiums. I am only running 1 and was curious how long each day to run it

I run VHO super actinic bulbs x 4 over each tank as well.

What they said.

I run my Radiums on m80s for 8 hours. 12 hours for my t5 blue+ bulbs and 14 hours for my vho actinics.
