Going Dark In Refugium?

[cathyg_99]

i have the same issue so i never bothered with a light, do you have an overflow??

i took my corner overflow and threw my chateo in there with some rubble for pods, then threw some egg crate over the pipe so its not sucked down into the sump so i didnt need to buy an extra light

Yes I have 2 of them. With 2 durso standpipes so there isnt a chance of it going in to the sump. My only concern is with the ph. I was just curious if others have run their refugiums with out a light.
