Ammonium chloride
Add 4 drops of solution per gallon of aquarium water to achieve an ammonia-nitrogen (NH3-N) concentration of 2 mg/L-N (2 ppm). Do not exceed 5 mg/L-NH3-N or NO2-N in the aquarium during cycling. Use an ammonia test kit to monitor your progress. 1 drop equals 0.05 ml so this bottle will treat 300 gallons.
Does this bottle have an expiration date or does it never expire ?
Yes. We recommend adding ammonia 3 times during the fishless cycling period and a 2 ounce bottle is enough to dose a 100 gallon aquarium 3 times. So plenty to cycle your 36 gallon tank.
Does this solution contain chlorine? The label says it's NH3-N but name is Ammonium chloride.
The product is ammonium chloride dissolved in pure water. It does not have any chlorine in it. The ammonia is measured in units of NH3-N

This was my first time starting an aquarium with actual ammonia. I fish-in cycled my first tank years ago and had always used media from that to seed. I had two small tanks I wanted to start up from scratch, and was very happy to see that Chewy carried this product, so I could get it at the same time I picked up other needed supplies. One tank was cycled and done in only a week, the other took three weeks. Love that it comes in a dropper bottle for easy dosing! It was easy to hit the 2.0ppm target.

This is great for cycling aquariums. It's cleaner than fish food and more humane than cycling with fish, and much faster than both. It will also prepare your tank for a much larger bio load than fish food or a fish in cycle. It's much easier and safer to use than ammonia you can buy at hardware stores.

Worked 1000x better than the 10% ammonia solution that I bought prior to using this. I will absolutely use this again for my fishless cycles.

The directions on the bottle are wrong. It says 4 drops per gallon. It should say ONE drop per gallon. I had to dump my entire tank and start over becasue the ammonia was so high. Very disappointed in this product.
