I am starting to notice threads of what I assume is algae starting to attach themselves to corals and rock work. They are dark in colour some thick some thin and in different lengths. If I gently blow a syringe of water at them they just disappear but always come back. There isn’t a lot of it and unless you were really looking probably wouldn’t notice it but I am starting to see it increasing in volume. I would like to be proactive in stopping it before it takes hold, what would you recommend I do?
