Hello fellow reefers. I am throwing the towl on this slight battle with hair algae. I'm not giving up but instead seeking some help. I have a few spots on my sand bed and rocks that have hair algae. What could I use or do to completely win the battle? I'm running a protein skimmer, filter Floss changed 3x's a week, clean up crew, strict 8 hour light schedule, chemipure, phosguard. Any help ?
