The filliment of cynobacteria is too small for a 200 micron nylon mesh filter sock to capture.
I almost forgot that I can revert my sieve screen into a floss packed water polisher.
I am going to try the RID-X and limit my lights. Eradication will be very difficult as cross contamination between all my tanks will be hard to prevent. Then every weekend I am boating in a lake full of the stuff.
