Had a massive outbreak of SCA, which I confirmed on the "Are you tired of battling" thread a few weeks ago. Before confirmation I had decided to add a refugium to my tank. I also adjusted lighting schedule in my display based on advice in dino sticky threads as well. Threw in a ball of chaeto, jar of pods, and dosed ~20-30 mL of phyto every day for about two weeks. Chaeto decided to start dying and nuked my tanked with nitrates and phosphates, and now my sand is completely clean of everything (had some cyano as well). Did I just get really lucky?
