algae
 

Ive got some reddish brown algae on my sand bed, never had it before, water quality is good, whats the easiest way to get rid of it. I got it after a pump killed a fish, did water change, everything is now stable, has been for a week , but still got algae

Cyano? Lots of resources, search this board for previous discussion. I think there's one going on right now.

wasnt sure of the name, thanks
