My ammonia has gone to 0ppm, nitrites are at 2.0ppm and nitrates are 40ppm. there is still only one small fish in the tank, and I am getting brown/red algae. Do I add fish to produce more ammonia the feed BB, Water change to reduce nitrites and add Aquasafe with bio-extract, or be patient and do nothing? Patients is not one of my strengths!TIA
