Treating Cyanobacteria in 8 Gallon Nano Tank

[BuschWacker]

I had some cyano in my nuvo 8 last fall. Treated with chemi-clean. It was gone after a few days. I always had a few traces of the same red and green in the sand against the glass. I recently got a pistol shrimp who has completely re-landscaped my sand bed. Exposed all the red and green. It has now all completely disappeared with no ill effects. I do weekly or more, if I can, water changes. Not a trace of it anymore.
