Hi everyone,

I'm new to the hobby. I've been trying to read up on stalled nitrogen cycles but my situation seems to be different from the trouble that most people have. I set up a 20 gallon tank about 3 weeks ago. My goal is to start with a pair of clown fish and eventually add some corals after the tank is more established in a few months. I started cycling my tank by using Fritz Pro Aquatic Ammonium Chloride and got my ammonia concentration to 4 ppm. I also added fritzyme 9 live nitrifying bacteria at the same time. A few days later, I thought I was on the right track because my nitrite and nitrate levels began to rise. The rest of my parameters have been stable the entire time: my pH is 8.0, my salinity is 1.025, and my temperature 78 degrees Farenheit. After about a week, my ammonia level was starting to decrease from 4 ppm, my nitrite level seemed to be somewhere between 2-5 ppm, and my nitrate level was somewhere between 80-160 ppm. As the last two weeks have passed, my ammonia level and nitrate level have decreased to 0, while my nitrite level seems to be stuck at around 5 ppm. What am I doing wrong? I know my cycle is not complete because my nitrite level is not 0. What am I supposed to do to get my nitrite level to decrease?

I appreciate any advice that anyone has to offer.

Thanks!
 
Large water change to get rid of the nitrate and get some fish
Thank you for the response. The puzzling part about the situation is that my nitrate has returned to 0 on its own but my NITRITE level has not decreased at all.
 
Nothing. Nitrite is not toxic to fish in that concentration.
Usually the test kit just can’t read that low.
Your cycled. Move forward slowly giving your good guy bacteria, time to up their pop each time.

This has to be faulty somehow. If you had nitrate unless doing a water change it wouldn't just disappear
 
Duuuuuh da. Duuuuuuuu da. Duuuuda duuuuda duuuda duuda da!

great thread agreed all

nitrite is no longer cared about in new cycling science, per Randys posts in the chem forum. How you prep your tank and fish against disease is what matters in updated cycling science. Begin study in the disease forum stickies

This was perfect. Well played on spelling the jaws theme as well lol
