I set up a new 10g tank for a qt setup. bare bottom, heater and large sponge filter. I dosed dr tims and followed his steps to a T. On week 3 I finally got zero ammonia. during the ammonia spike it never went over 2ppm. I tested nitrite on week 3 and had over 200ppb on my hannah I used a api nitrite test that my GF had for her beta tank and it showed 5ppm as that was the highest reading. My hannah reads in ppb and I didnt have any other test so that's why u used her api. Api makes a nitrite test that works for both marine and fresh water so I assumed the test in her "master fresh water" test kit would be the same formula. Idk why they would make a test for bother systems but only use a fresh water test I the master fresh water test kit. 3 days ago I did a 50% water change per Dr tims steps and today I'm still reading 5ppm or more. Do I just continue to wait or did it stall and I need to start all over or do another partial water change? I emailed Dr Tim and haven't received any email back. Thanks.
