Any good suggestions to help control hair algae? My 55g does not have a sump or refugium (just got an Aquafuge, not installed yet), and over the last 3-4 months has developed a "healthy crop" of algae. My lawnmower blenny does not seem to ever graze on it, but certainly likes the mysis shrimp and nori. Anyone have much luck or experience with lettuce nudibranchs or have other suggestions (short of adding a sump/refugium - not an option due to space). Thanks for any ideas!
