I have a 36 gallon bowfront and an 10 gallon that i recently got. I didnt add any ammonia the first week was waiting to get dr tims pure ammonia in the mail. Well now that i added that into both tanks they are at 4.0 and 0 nitrite and 0 nitrate and has been like this for 12 days now. Iv only added the ammonia once and it hasn’t gone down at all. Am i doing anything wrong? I do have a couple live plants not sure which and i use api stress and coat as conditioner for water. I only changed water in the 36 gallon when i replaced substrate from dirt to sand and then i added the dr tims ammonia the first week.
