Chemiclean not working?

[Spyd]

Lots of different things can cause cyano outbreaks, old lamps, dead flow areas, excess nutrients, etc. Bio-pellets tend to cause cyano as well. I found dosing MB7 once a week, while running pellets, allowed me to stop any cyano blooms. I also turkey bast my rocks once a week and stir up my sandbed every 2 weeks to prevent any dietritus or gas build ups.

Chemiclean works great for removing cyano, however, it really is a bandaid fix most of the time. Whatever caused the cyano in the first place is still present in your setup and may cause it again over time. Also, the more and more you use chemiclean, the harder and harder it is to remove the cyano.
