Has anyone ad this happen before. Setting up a new 10g observation tank. Started it with Dr. Tim’s one and only. Got through the cycle pretty quick in about 9 days. On the 9th day your supposed to add fish but the fish weren’t going to be ready so I contacted Dr.Tim and they said to add more ammonia every 3-4 days. Day 12 I added more ammonia. Day 13 my nitrites shot up to 4 ppm using Salifert test kit. Called Dr. Tim said do a 25% water change which I did. From day 14-29 nitrites didn’t move. They stayed at 4 ppm. Did a 25% water change. Nothing happened. By day 35 nitrites still reading 4 ppm. I thought maybe it’s the test kit so I checked it with a Hanna checker and it read 2 ppm. I have a hard time distinguishing the colors on different test kits so maybe it was 2 ppm all along. But it still hasn’t changed. Day 41 did 50% water change. Still reading 2 ppm with Hanna checker. So from day 14 to now which is day 42 nitrites have neither gone up or down. Ammonia is at 0. Question is should I ride it out,add more bacteria or drain the whole tank and start from scratch? Thank you for any advice.
