Seems fine. It's just a case of waiting for those nitrite eating bacteria to multiply. Those often are a bit slower than the ammonia eating bacteria. You should find that once it actually starts to come down, it will do so reasonably quickly.
Keep your chin up and stick at it. It won't be too long.![]()
As its taken nearly 4 weeks for the ammonia to start gettin processed, am i looking about the same time or even more for the nitrite?
Also when doin a test for NITRATE using an API Wwater Test kit, it sais wait for 5 mins before matchin color. Nitrate comes at about 10, but If i leave it for another hour or so it changes color even more... to about 40.
