Ingredients

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

    Measure with a syringe

    By Quin on May 6, 2021

    Instructions on the bottle are in drops, 4 drops per gallon raises ammonia to 2ppm. But! The drops the come out of the top are bigger than normal drops! Dont overdose your tank, measure with a syringe or teaspoon (1tsp=100 drops=25gallons) Works great and as intended when you measure properly.

    Pretty good

    By FishMom on Mar 10, 2021

    I'm new to the cycling process but this speeds things along. I was "ghost feeding" to get my ammonia reading and that was going to take awhile. The only thing is for a 20g tank the 4 drops per gallon brought my ammonia reading to 4ppm instead of the listed 2ppm. No problem, just be aware. It took a week to build nitrites and nitrates, but once ammonia/nitrite read 0/.25 I redosed with ammonia and went right back to 4ppm. Waiting til it drops to 0/0 and then I can add my fish to his new tank! Looking at 2-3 weeks vs 6-8 weeks. Win!

    Directions are not correct

    By Matthew187 on Feb 8, 2021

    Product works great for dosing ammonia. A lot safer than hardware brands that you dont know what else has been added. However start with 1 drop per gallon and test and and go up from there. As a lot of people say 4 drops per gallon is way to much. I ended up at 2 drops per gallon to get to 2PPM. Also be sure to dose to the actual gallons of water in your tank not the aquarium size. You can easily add to much.

    Great product, amazing turnaround time

    By Ryan on Dec 7, 2020

    I am starting a fishless cycle. I ordered this on a Sunday morning and then received it just about 24 hours later. I was not expecting that and couldn't be happier with both the product and Chewy.com

    Cheap and Easy

    By ScottishPrincess on Sep 30, 2020

    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 Brock on Aug 31, 2020

    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 Happy on Aug 8, 2020

    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.
