Early signs of Cyano

[Tracey2]

Manually remove it without stirring your sand bed and blast it off your rock, lots of flow and keep water perimeteres stable. I am battling this nasty stuff and I can't say that I have won the battle yet but I do find its worse if I let something get out of wack, like mag or kh or if I make any sudden changes like a water change without being sure my new sw matches the tanks. I think the most successful/clean tanks are very stable.
