Okay so I spent lots of time running around the archives, but i am still a little bit unsure. Does cyano require light to grow, i seem to be engaged in a losing battle against it in my tank :x . Will leaving the lights off for a couple days have any effect on it? (just wanted to try 'natural' methods before i start chemical/absorbers etc!)
Thanks - Jon
