I currently have a 15g growout tank with about an inch of sand. I have an algae problem - can't tell if its bryopsis or hair algae. Everyweek it grows/clings to the rubble that I have frags mounted too and there are tufts sticking to my sand.

I have a 6 gallon refugium I'm about readt to add. I plan to remove all the sand in the grow-out tank. Would it be advisable to use this sand that has had the bryopsis or hair agae in it and throw it in the fuge or start with new sand in the fuge?

Thanks!
