Hi I have a Red Sea Max S 650 - for it is approx 1 year old. - for the last 2-3 months I have been battling what appears to be "black hair algae" ??
It is covering Sand and Rocks.
I have attached a video and would be grateful if you could help identifying it for me and help with how to get rid of it.
