Hahah im sorry there just a ton of confusion.Oh I thought you just did the black out and the bacteria in the morning. I did not see where you said you did the peroxide.
Originally I did 3 treatments of redslime remover for it to only get worse. Then I realsied my phosphate was 0.00 . Did a 4 day full blackout and been dosing phosphate to maintain a level thinking it was dinos wich for a month had no change (came back in days) I made this thread and was told by Mr vette that it is indeed cyano. Orginal suggestion was no need for a blackout and just to reduce lighting and dose bacteria wich made 0 impact and only got worse. Now he recommends doing a 5-7 day blackout with peroxide dosing. Wich I have just dosed my first dose into the tank.
