I have a 13.5 fluvial tank that’s been running for 5 months-ish and I’ve always had hair algae issues with this tank. I keep the water a bit dirty on purpose since it’s my LPS and softies tank. What’s the best invertebrates or fish to get rid of the hair algae? I’ve tried getting rid of it by hand, brush, siphoning out. But no matter what I do it stays and I’ve had no luck with lettuce nudibranchs and obviously I can’t get a sea hare or tangs in here. Thanks!
