Using Pure Ammonia to Cycle the Aquarium
Instead of using fish food for ammonia production, we can also introduce pure ammonia to the tank.
After the tank has been set up (see above), add 5 drops of ammonia per 10 Gallons into the water on a daily basis.
Ammonia will rise to 5 ppm and higher. As soon as nitrites are measurable, reduce the ammonia input to 3 drops per day. Nitrites will rise to similar levels. Keep adding 2-3 drops until the measurements of ammonia and nitrites come out with 0 ppm. The tank has then completely cycled.
Seeding the tank can significantly enhance this process. 7 days for a complete cycle are not unheard of; otherwise this methods takes 2-3 weeks.
The bacteria colonies, using this method, are certainly large enough to handle a well-stocked aquarium.
