Hello! I am new to fish keeping and recently I bought a 10 gallon aquarium starter kit from topfin. I did a lot of research before buying the tank, the cycling and what to get, and I was able to get it cycled. I let the tank cycle for about a month (January 22 to February 22) (I did add apI quick start during the month) before buying the 3 glofish tetras on febuary 28th. At this time, the tank had 0 ammonia. The next day I went to check the water with an apI master test kit, and saw the ammonia level spiked. I knew that there would be a spike in the water at the beginning, so I let the tank cycle for a week (February 29th), then checked the water again, to see that the ammonia was still at 8.0 ppm. I did a 25% water change yet the ammonia did not go down. I heard that if I did a 25% water change every day for a week it would cut down. It didn't. currently I have done water changes from March 2nd to March 5th. I have not done a water change today (March 6th). I have as well added seachem stability daily since March 2nd, (as it said on the instruction, today is day 3 of adding it, as it says add one cap per 10 us gallons on day 1, then add a capful for each 80L (20 gallons) daily for 7 days, therefore because I have a 10 gallon, I add half a capful) As of today, (March 6th) I tested my water again, and I had 4 ppm ammonia 0.25 ppm nitrite and 5.0 ppm Nitrate. My Ph is at 8.0 and the temperature of the water is 75.8 degrees Fahrenheit (24.3 degrees celcius). I recently bought a new filter yesterday, (March 5th) Upgrading my filter from a topfin whisper 10 to a Aqueon quietflow 10. Is there anything I'm doing wrong? What can I do to bring that ammonia down to 0 ppm?
