Just an update because this is real world testing and I am holding nothing back. Prior to changing my gravel, my ammonia and nitrite levels were at 0 so I was not overstocked and my filters were handling it and working properly. When I changed my gravel to another kind, my ammonia level went up and that is when I added the stability. Well the first dose of stability was at night on 5/28. Today is 6/3. Sad to say, that my ammonia is at 2 and my nitrite is at 0.25. By this day, I thought my water would be better.
