Have about a 5 inch circle broke out on a rock. What's my best route before this gets out of hand?

If cyano then Chemiclean will knock them all..

I wouldn't dose ChemiClean for one 5" spot....just siphon it out and increase your overall flow in that area...cyano usually grows in lower flow areas...
keep an eye out for more and if it persist and you continue to see more buildup of cyano, then I'd dose ChemiClean

Think thats the plan slow feeding siphon off change gfo lower temp. Think it started as I raised my temp to 78 79 and was trying to raise po3 a bit.

Changed gfo water change and vacuumed right out. See what happens.
