I will soon be building a DIY algae scrubber for my refugium. All the research I've done suggests the light cycle for it should be similar to the light cycle for my refugium, which I get. My question is, do I still need to run a light cycle on my refugium, or only on the scrubber? The light from my scrubber will likely not bleed out into the refugium if I build it right. Any help is appreciated, thanks!
