So I had very bad cyano problem in my tank,I went and bought some chemiclean and in a day every single piece is now gone. Was on the rocks,sand bed was bad and stringy red slime. I' very happy how this product worked and would definitely recommend it to anyone having the problem I had. Just wish I went and bought sooner.
