Hopping on this thread, I've had a hair algae problem recently after successfully battling a dino outbreak. Long story but tank is low nutrient sps dominant mixed reef and I was probably overfeeding with oyster eggs and then stopped carbon dosing cold turkey and the dinos came (big mistake when I switched from kalk/vinegar to CaRx). Dinos taken care of and hair algae is present. Phosphates are now under control. Doing some physical removal and just hoping it will die back over time now that everything has stabilized.
Any thoughts here?
