Have a fluval evo 13.5 tank. Been a week of cycling so far. Added in Fritz zyme 9 to speed up the process but I didn’t add any ammonia in with it. Readings are currently ammonia .5ppm, nitrite 5.0ppm and nitrite 160ppm. I feel like the nitrate and nitrite are a bit high. Not sure if I’m doing anything wrong or just let the process keep going. Maybe a water change is necessary to get those levels down a bit. Should I add fish food to get more ammonia into the tank and see if it processes and lowers the other stuff. Also not running any lights, no carbon, no skimmer, oh and there are no livestock in the tank at this very moment. Don’t want to kill the bacteria that is forming in the tank. If someone has any suggestions or advice that would be awesome
