I apologize if this is the wrong place to post. I’m new to forums. I recently purchased a 36 gallon tank. At the time, I didn’t really didn’t understand cycling a tank. On April 14, I added, a little bit of fish food in it and ran the filter. On the 16th, I put in a goldfish and a molly. On the 18th, I added 8 neon tetras, a small angel fish and 5 guppies. On the 20th, I finally understood cycling and brought test strips. On the 20th, the readings were ammonia .5, nitrite 0, nitrate 20. On the 22nd, the readings were ammonia .5, nitrite 0, nitrate 20. On the 24th, the readings were ammonia .0, nitrite 0, nitrate 20. On the 26th, I thought perhaps test strips were not accurate and bought a API testing kit. The API readings were ammonia 0, nitrite 0, nitrate 20. I also did two 10-15% water changes since placing the fish in the tank. I am puzzled. Why didn’t I see get any nitrite readings. None of the fish have died. Is my tank already cycled? What do I need to do? Thanks in advance.
