Claim checked: "A tank is cycled after a fixed number of weeks"

What is supported: microbial nitrogen processing can become established in aquarium systems.

What is not established: age, nitrate, clear water or a bottled product alone does not prove that one tank can process its intended load.

Do next: test a known fishless challenge and preserve total-ammonia and nitrite reporting bases.
