Review on 🐠 100% Natural Aquarium Treatment for Fishless Cycling – Chlorine-Free, Ammonium Chloride Fish Tank Cleaner for Freshwater, Saltwater, and Reef Aquariums by Dr. Tim’s Aquatics by Ben Karlen

This bottle contains ammonium chloride and will add ammonia to your tank to start/speed up your cycle (combined with good bacteria). The problem is that it's more concentrated than what the label says. The label says to use 4 drops per gallon to raise the ammonia to 2ppm. I dosed 4 drops per gallon and the ammonia level was 8 ppm. I would suggest starting with 1 drop per gallon and see where that gets your ammonia. Then increase the dose if necessary.
