Cycle Stalled? Why Ammonia Will Not Drop (Checklist)

Ammonia stuck at the same reading for days? Work through this order-of-operations checklist before assuming your fishless cycle has failed.

Most fishless cycles finish in roughly 4-6 weeks, though the honest range runs 2-8. Here is what actually speeds it up or slows it down.

The nitrogen cycle turns toxic ammonia into nitrite, then nitrate, using bacteria. Here is why each stage is dangerous and what it looks like.

Cycling means growing beneficial bacteria to turn toxic ammonia and nitrite into nitrate before fish go in. Here is the fishless method, day by day.
