DrTim’s Aquatics Ammonium Chloride Solution – 8 oz – Fishless Cycling Formula for Freshwater & Saltwater Aquariums – Treats 400 Gallons

DrTim’s Aquatics Ammonium Chloride Solution has been a game-changer in setting up my new aquarium. This reagent-grade solution simplifies the fishless cycling process by providing a precise ammonia source, eliminating the need for guesswork. When used in conjunction with DrTim’s One & Only Live Nitrifying Bacteria, I was able to establish a healthy biofilter in my tank without subjecting any fish to harmful ammonia or nitrite spikes. The easy-to-dose liquid formula treats up to 400 gallons, making it both efficient and cost-effective. I highly recommend this product to both novice and experienced aquarists aiming for a safe and effective aquarium setup

Got the job done. 1 ppm was just fine for me though the 2 ppm would have been a lot.

I read to use my fish food to create ammonia for my cycle, COMPLETE LIE. I'd have needed to use 15 cans of it to produce the affect needed to cycle my fish tank. With 4 drops per gallon of this you can quickly produce the ammonia needed to start your cycle. It took 7 days and I had Nitrates and Nitrates and a LOT of them. My tank finished cycling right on schedule thanks to this product. I would have been monumentally screwed otherwise and if you're new to this please heed my words and use this to cycle your tank (FISHLESSLY OF COURSE) because it will save you time, frustration, and lack of understanding what's going wrong.Set up your tank. Use this. Get the right readings for Nitrates. Add your fish.That simple. I now know how to cycle a tank thanks to Dr. Tim. Enjoy this picture of my healthy thriving tank.

used this to get a good bacteria cycle for my axolotl tank. it worked perfectly

This stuff helped cycle my tank pretty quick. I was using it with Seachem Stability and saw nitrites show up in just a couple days, which was way faster than I expected. It’s a clean ammonia source and didn’t cloud the water or mess with the pH. Only issue I had was with the dosing—it says 4 drops per gallon but the cap has different markings and it’s not super clear how much to use if you need to redose. I ended up just testing a lot and going by that. Still, it did exactly what I needed it to do and I’d use it again, just wish the instructions were laid out better.

(Left before adding, right is after.) Works great, I also realized I was using my ammonia testing kit wrong because of this lol! Now that I know how to properly use it I’m really excited! I’m filtering my quarantine tank before getting my first fish. Works great and fast. For accurate reading give it a couple minutes so it mixes properly in the water!!

Bought a smaller version of this off amazon for a fishless cycle in a 10g bucket. Added half the bottle into with zero reading. Tested just the solution and got zero reading.Thinking it was a one time error got this one, same thing. No idea if theyre from the same batch but there was no ammonia smell and no reading when testing the solution by itself.Shame because I cant even return for a refund. Ended up getting powdered ammonia chloride. Working well. Maybe I just got unlucky but beware.

Clear instructions on how to use. Cycled my tanks quickly and would not use any other product for cycling any fish tank. Dr. Tim's videos on YouTube coinside with the product so any questions how and when to use the product is explained.
