If you set up a refugium to keep algae away from the main display I’d say you’re definitely on the right track with your refugium. The more algae in there, the better. Unless of course it’s a Display refugium, then you’re gonna need a good way to clean the glass just like your main display, if you want to make it look good too. Typically refugiums are supposed to be messy for the sake of our display tanks to look neat so it’s really no issue Sent from Singapore Reef Club mobile app
