This is the worst I have ever had cyano
and it was only on one side of my tank. I purchased a powerhead specifically to point down to this area to add more flow right onto the cyano
. That didn't do anything in terms of making it go away. Controlling nutrients and removing the cyano
manually are most important, IMO
. I got that all cleaned up and my sandbed is looking pretty good. I have never had it on the rocks.
