Reverse Daylight- or 24/7 Refugium Lighting?

I have been running my refugium for a few months now and have gotten over the curse of Cyano outbreak and it’s now limited to just a bit on the top of one of my foam sponges in there. I had a decent sized hunk of the Chaetomorpha (sp?) macro algae in there and it has seemed to stay the same size all along. I was waiting for growth for weeks and weeks with very little change. I had been using a small 15 watt daylight bulb (power compact) that I kept from my freshwater lighting. I recently upgraded to the CPR 36 watt bulb/fixture. This is a 7,300 K bulb. It didn’t seem to make too much difference either after using it on 24/7 for about a week. Last night I turned that light off and left it off until the next day about the same time. Then when I turned it on, I noticed significant growth in my Chaetomorpha. Would this be because of the new, more intense light?
