Do you need lighting in a refugium if you don't have chaeto?

[sawdavis]

I have had a terrible outbreak of GHA and finally am resorting to Vibrant dosing. Anyway, I have been unable to keep any Chaeto in my refugium alive since . Do I need to keep the light on my refugium if I don't have Chaeto? I have the biocubes in there, live rocks and I put pods in there. Buy won't those just gravitate to the display tank if there is no light on in the refugium?

The only reason for a light is to grow algae. Thus, if you have no algae, no reason to have a light on. Pods will do just fine in the dark.

I second no chaeto, no light. Nothing needs it in there - kali

I have read several claims that Vibrant kills chaeto, btw.

Of course it does. Vibrant is non discriminatory and will kill macro algae’s as well. That’s what it does, kills algae.

Then call me Captain Obvious, lol. Just wanted to make sure OP was aware.

I know about the correlation with Vibrant and Chaeto. But I have tried everything to get rid of the GHA and nothing worked so have been dosing Vibrant now for about 8 months. I'm not sure that is even working as I still have it, though diminished, but that might be due to my daily handpicking it off the rocks. I read and did and do everything on the list that BRS recommended: urchins, clean up crew, lawnmower bennie, scrubbing rocks with peroxide, keeping phosphate zero, raising Mg to 1400. No significant change. Very exhausted.
