Nitrite is produced continually during the ammonia cycle by nitrifying bacteria in the biological filter. While not as immediately toxic as ammonia, any accumulation of nitrite should still be addressed as soon as possible. The nitrite level will eventually be broken down to non-toxic nitrate. Regular testing for nitrite is recommended - chronic exposure to even low levels of nitrite can cause brown blood disease in fish, which can cause suffocation and death.
Dosage/Instructions
To remove childproof safety cap, push down while turning.
1. Fill a clean test tube with 5 ml of water to be tested (to the line on the tube).
2. Add 5 drops from Nitrite Test Solution, holding dropper bottle upside down in a completely vertical position to ensure uniformity of drops added to the water sample.
3. Cap the test tube and gently shake several times to mix solution. Attention! Always use the cap. Avoid skin contact as this may affect the test results.
4. Wait five minutes for the color to develop.
5. Read the test results by matching the color of the solution against those on the Nitrite Test Color Chart. To reduce nitrite: reduce feeding, perform partial water changes, add Fritz Complete water conditioner to neutralize any nitrite present, and add FritzZyme nitrifying bacteria.
