Hey I have been cycling my 10 gallon for the past three weeks. I seeded it with filter media from my established turtle tank. Now I have made a big error I believe as my Nitrite is at 0 and my ammonia is at 0. All the while I have been testing my nitrite hoping it would go up to spike. The highest it ever approached was .50. Was that the spike? I confused NO2 with NO3 so I think my tank is cycled? Can anybody verify?
