Cannot get rid of cyano!

[waynemah]

I've been battling a little of it myself. 10% weekly water changes and have a slightly better regulation on food. Pellets in the morning (lasts about 20 seconds) and a cube of mysis and bloodworms in the evening. This is for a well stocked tank. The Cyano has diminished to almost nothing over a period of a month or so. Fish are seemingly healthy and plump.

Another method is to perform regular water changes for a while to reduce nutrients, then hit the tank with chemiclean... If it comes back there is some sort of food source, if your lucky it won't.
