My new tank was ammonia free for 6 weeks since first planted and nitrite lvl 2 ppm remained a constant.. I used this product to restore the cycling

Great product. Used for cycling my axolotl tank. Beware, it is stronger than you think. We used half the recommended dosage for accurate ammonia readings.
