I have a question. I have been testing my water in my aquarium and the nitrite level is .50 and the nitrate level is .25 but the ammonia levels are zero. I have been doing water changes every other day but stiill no change in the levels and the fish seem to be acting fine. My aquarium is about a month old. How do I lower the nitrite level, should I do water changes, because when I do the water gets cloudy for a few hours. OR should I just leave it alone unless the fish seem stressed and let it finish cycling? BTW the aquarium is 55 gallons and I have 9 fish, most are small. The pH is around 7.8. Thanx!
