I got a baby biorb for Christmas did not realise about fishless cycling, got 3 fish in tank 2 platys 1 guppy lfs said would be ok. After looking on Internet discovered the cycling process. 4 weeks in decided to test water with api test kit ammonia 0.5ppm, nitrite 0.3ppm and nitrate 40ppm. Following lfs advice did 50% - 20% water changes daily until ammonia gone down to 0 and nitrite 0. Have also syphoned media once and rinsed out filter in tank water once. For past 2 weeks or so ammonia has been fluctuating between 0-50ppm and nitrite gone down to 0ppm and nitrate 20ppm. Am I just impatient? But ammonia will not stabilise was under impression once nitrate are high and nitrite 0 cycling process over. Is my tank still cycling? Or is it a problem with stocking, fish waste, or over feeding. Have been feeding 1 flake per fish every other day. Any advice would be much appreciated why ammonia will not stay down?
