Hello everyone, I have been cycling my tank for over a week now and I already got my ammonia spiked and back to zero as well as my nitrare is way above 160ppm as this point. However, my nitrite level had been at 5ppm for for than 3 days now. Should I do anything at this point? If there is no issue than whnlen should the nitrite level start to go down after the ammonia level hit 0? Thank you.
