So about a week (March 4th) ago I began the process to cycle this new 5.5 gallon tank in preparation for my betta. New everything. Treated and aged the water. Dosed pure ammonia up to 5.00 ppm, and slowly watched as the levels went down to about 1.0 ppm but tested nill for nitrate and nitrite. Two days ago, March 11th, re-uped the ammonia to 5.0 again. Checked today and it looks around 4.0 ppm. So slow. My betta is blowing bubbles in his bowl thanks to the warmer weather however. Where do the nitrogen cycle bacteria come from anyway to populate a totally new tank? I wish they would get in there and get on with it. Sorry for the useless post.
