Have you checked your posphates or silicates? How often do you change your phosguatd? Is it exhausted? If you have a lot in the system, this stuff is going to exhaust faster. Its only going to keep a stable system, stable at 0 once its already there.

I am going to make a comment that always causes a stir from experienced hobbyists, but has always worked for me in the past. Upon the first signs of cynobacteria:

1) increase water flow in the area.
2) increase alkalinity to 12-14 dkh.
3) maintain calcium at 400-460ppm, not dropping below 400ppm.

I have found this to work on multiple instances personally in my home aquariums.

I couldn't argue with any of that, but the ALK seems really high for my taste, other than that. Good stuff.
