I got a little lazy for a while and had hair algae growing. I manually removed 99.9% and added phosgard to bring my phosphates down and that needed up tanking my phosphates. A few days later I had dynos growing. It was all over my rock and sand. I manually removed most of it and killed lights for a few days and it was 99.9% gone. It’s been a few weeks and I can’t get the last little bit to stay away any advice? I did add a Uv sterilizer and my water perameters have been stable for a few weeks. Tank isn’t new it’s a few years old and well established.
