I have been fighting with a cyano outbrak for awhile now. I have managed to get it off of my sand and rocks but not off of the GSP colony. I have used a brush to gently remove it and have also been dosing chemiclean to kill the cyano. In all it has worked but not on the GSP. Im slowly seeing the polups diapear and the cyano taking over on the base purple matt. Any ideas?
