Day one added DrTim’s Aquatics One & Only Live Nitrifying bacteria to 50 gallon. Also added 4 drops for every gallon, 200 drops. Day 2 – Measure ammonia and nitrite. Day 3 – If ammonia and nitrite are below 1 ppm add more ammonia: four drops of our ammonium chloride per gallon (check the label). so my ammonia is 2ppm and nitrite is 0 so im guessing im not suppose to dose..
