I have this same question. Is there an ideal turnover rate for macro algae based refugium for fast growth of macro algae?

Since I already have the Kessil A160, I started with it. If it does not work, I will buy one of those cheap grow lights.

Hi, I am thinking of setting up a refugium to grow chaetomorpha. I have a spare Kessil A 160WE Tuna Blue bulb. The lowest spectrum on it is 10K i believe Can I use this bulb at it's most white setting to grow chaetomorpha. Or would be right to buy one of those red colored lights for refugium? If this is not the right forum to ask this question, mods please feel free to move it to the right one. Tank info: RedSea reefer 170, mixed reef tank.
