A simple guide to nitrite, nitrate, and what they tell you about the aquarium cycle.
Nitrite should be 0 in a betta tank. Nitrate is less immediately dangerous but should be controlled with water changes, plants, and careful feeding.
Nitrite appears during the nitrogen cycle and can be harmful to fish. A cycled tank should show 0 nitrite.
Nitrate is the later product of the cycle. It is managed with partial water changes, plant growth, and avoiding excess waste.
Ammonia, nitrite, and nitrate together tell a better story than any one test alone.
