Ok so i understand that Ammonia gets turned into Nitrite which brings the ammonia level down.
I know that then the Nitrite gets turned to NitrAte, which brings the nitrite levels down.
But what brings NitrAte levels down.
My tap water shows a 25mg/l level of NitrAte to start with. And so turning Nitrite to Nitrate i thought i would see it rise, but instead my Ammonia is 0, Nitrites are going down and so are my NitrAte levels.
What is happening to the NitrAtes???
