My local WWC had told me that I needed to run my refugium light the opposite of my tank light schedule. I was unclear on what he was exactly talking about or why he said that so I came here. I was thinking maybe he said that because he thought my tank light would be providing my refug with light that would grow my cheato, but that is not the case. My tank light provides little light to my refug chamber so I was wondering why I wouldn’t just run the light full time to get optimal cheato growth. Maybe it’s just better to run the light during the night for some reason? Please share if you have any experience with this or could explain this to me. Thanks!
