FAQ
How long does a fishless cycle usually take?
Most tanks cycle in 3-6 weeks depending on temperature, bacteria seeding, and ammonia dosing consistency.
What ammonia level should I dose to?
A practical target is around 2 ppm total ammonia, then redose only when ammonia and nitrite are processed quickly.

When your tank can process a full dose of ammonia to zero ammonia and zero nitrite within 24 hours.
