You could try adding 5 drops of pure ammonia per 10 gallons. Test it about 30 minutes after just to get a reading to go by. Test the next day around a similar time and if its at zero, its probably cycled. If you still have ammonia readings then you are not cycled and you need to add ammonia everyday until you get 0 ammonia, 0 nitrites, and a reading on nitrates. Here is how you can do it:
Using Pure Ammonia to Cycle the Aquarium
Instead of using fish food for ammonia production, you can introduce pure ammonia to the tank.
After the tank has been set up, add five drops of ammonia per ten gallons into the water on a daily basis.
Ammonia will rise to five ppm
and higher. As soon as nitrites are measurable, reduce the ammonia input to three drops per day. Nitrites will rise to similar levels. Keep adding two to three drops until the measurements of ammonia and nitrites come out with zero ppm
. The tank has then completely cycled.
Seeding the tank can significantly enhance this process. It is possible for a cycle to complete in seven days with seeding; otherwise this method takes two to three weeks.
The bacteria colonies produced using this method are large enough to handle a well-stocked aquarium.
Some aspects to consider
The tank has to be well oxygenated because the bacteria require oxygen.
The ammonia used should be free of any perfumes and additives.
Do not treat the water with conditioners that remove ammonia.
