So earlier today I found out that my tank is officially cycled Ammonia 0, Nitrites 0. I started July 30th and today is August 15th. I did a 50% water change because I wanted to clean up the tank. After the water change the ammonia spiked about a .25, but nitrates are the same. So my question is will the nitrites eat that ammonia or will the ammonia dissipate after a while? This is a fishless cycle. I poured water in my tank and then immediately added conditioner. 15 gallon tank using prime and fish food for ammonia. Temperature around 80. Should I had only done a 25%? Or should I have added the conditioner to the tank before the tap water? How badly did I just mess my cycle up? And to add there hasn’t been any ammonia blooms.
