GBrymer Posted August 5, 2022 Share Posted August 5, 2022 Have any of you heard of or experienced Flourish Excel stalling the cycling process in a new aquarium? I have a new 20 long planted aquarium with minimal fish (2 corys, 1 female betta) and 7 plants that’s 5 weeks old. The cycle appears to have stalled with nitrites for about the last 3 weeks. I was told that the problem could be the Flourish Excel killing some of the beneficial bacteria and stalling the cycle. My plants are doing amazing and the fish are health, but I’m doing daily water changes to keep the nitrite levels down; 25% daily. Any suggestions? Thanks in advance.
