UPDATES:
Since I changed the water later last night, I decided to wait for the levels to be checked today. Around 10:12AM EST time, these are the following parameters:
Ammonia: 2ppm
Nitrite: 1ppm
I am happy the ammonia went down considerably. I didn't put any flakes still. I will wait till tomorrow and see if the levels will change. If it is still 2ppm, then maybe I can put a little amount of flakes in it.
