My 10g fish tank is or was going through the fish-in nitrogen cycle. I'm a beginner so I had no idea what the nitrogen cycle was until I did research after I got fish and put them in the tank. I gave my self new tank syndrome. Here is the situation. My ammonia was through the roof for about a week and half to 2 weeks. Then is started to drop. When that happened the nitrites rose through the roof. But then a day or two later the ammonia and nitrites were both holding at .25 and lower and not rising or falling. I use the API master test kit. Then I used Tetra easy stripes to test the nitrates and they are at zero, they never had a jump or anything. Its been about a week now and nothing has started to rise, so is my tank done cycling? I started to use Seachem Stability to help with the nitrogen cycle. Could this have sped up the process and that's why my nitrites dropped so fast? Any answers would be great! I posted a picture of my water quality for ammonia and nitrites.
