Ammonium chloride

Instructions

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.

FAQ

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

    Cheap and Easy

    By on

    I feel that using fish to cycle a tank is not humane, so I opted to do a fishless cycle using this product along with a bottle of beneficial bacteria to cycle my tank. I had established media that I borrowed from one of my other tanks, but needed to triple the capacity as this new tank was huge. This product worked GREAT. As others have stated, the dosage as instructed seems to be too high. I used 1 drop per gallon of water and it worked perfectly, granted I already had colonized media in my filter, so maybe 2 drops/gal would be ideal for a brand new tank.

    Directions can’t be right.

    By on

    I followed the directions and the video available on YouTube and the company website. Thankfully I did this before adding any fish. My ammonium went through the roof, at 8 ppm or higher since the testing only goes that high. I ended up adding a second bottle of bacterial in hopes to bring it down, which is has started to come down, but certainly not like the video explained. I may follow the video and once the ammonia is at zero do a second run with way less ammonium. If it wasn’t for the fact that the bottle of bacteria is over $20 for 4 Oz, I would consider dumping all the water. I’d you buy this beware that the directions cannot be accurate.

    Dr. Tim's Aquatic Aquarium cycling Solution

    By on

    This is the first time I am trying this product, was not aware there were other steps. I found the info on the bottle, went to the website to find the necessary process, additional needs and more. I even found many answers no one else even addressed when I made my inquiries locally. Bit pricy, but if it works & solves the issues with my tank restart, I am going to definitely repeat with my other two tanks. After three years, this is the easiest most informative information I have found in one location.

    Works for Cycling

    By on

    This product is actually really good to start your aquarium. The bottle is small and convenient. However when squeezing the bottle I kind of wish it did droplets instead of a spritz. I don't know how else to word that. Maybe I don't know my own strength. But when you gently squeeze the bottle a lot comes out of it instead of droplets, You have to be really careful or else you'll end up putting too much ammonia in your tank

    Precision Product

    By on

    A very convenient option for fishless cycling when you want to know exactly how much ammonia you're adding (vs adding fish food or a piece of shrimp). Made it easy to dose our tank as needed to get the cycle going.

    Excellent for a fishless cycle

    By on

    Great product for cycling any aquarium, follow the instruction and make sure the ammonia levels reaches 1-2ppm then let the bacteria grow. Highly recommend!

    Be Wary of Dosage

    By on

    I'd suggest Dr. Tim's to everyone. It is much easier and safer to fishless cycle this way, and it gives me peace of mind that there are no harmful additives. Additionally, Chewy.com has the best price anywhere on this product. The reason I only gave the product 4 stars is that the dosage suggestion on the bottle is inaccurate. To dose to 2 ppm of ammonia, I only had to add 2 drops per gallon.

    Need to use this with Dr Tim's bacterial treetment.

    By on

    According to Dr Tim you need the ammonia for the bacteria to feed on until established. Worked great.

    Great Product

    By on

    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.

    Fast cycling!

    By on Top 500 Contributor

    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.
