Dr Tims Aquatics Ammonium Chloride Aquarium 100 Natural 2 Oz Dr Tims Aquatics Ammonium Chloride Saltwater Freshwater and

I have used Dr. Tim’s Ammonium Chloride in two separate tanks. First my 5-gallon freshwater tank, and now my 10-gallon and it worked exactly as advertised. This product is perfect for anyone doing a fishless cycle using bottled nitrifying bacteria. ✅ Pros: Accurate dosing: The included dropper cap makes it easy to measure the right amount. The instructions are clear—4 drops per gallon for 2 ppm of ammonia. Safe & pure: No added dyes or surfactants that could harm beneficial bacteria. Speeds up cycling Great for beginners: It helps to follow the schedule instead of guessing if it is working or not. This is not a stand-alone cycling product—you’ll need to add a nitrifying bacteria culture or have an established filter for faster cycling. Test your water regularly with a liquid test kit to monitor progress. I love the API Freshwater Kit. If you're serious about fishless cycling, Dr. Tim’s Ammonia is a reliable and safe option that gives you full control over the process. It took the stress out of my first fish tank cycle, and I’d definitely use it again for future setups. Read more

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 Read more

Works perfect for fishless cycling! I now have two cycled tanks and so much ammonia left. I’m so happy. Honestly, they could be sold in smaller bottles because I didn’t need that much for my 20 gallon, 5 gallon, nor 10 gallon. My nitrate levels are still kind of high though Read more

This did the job for continuing my fish-less cycle. I had started the cycle using food but was recommended this and I’m so glad I went with it - my tank cycled itself within a week or two after pivoting to this product (7 weeks total to cycle). I wasn’t getting any good readings before this stuff entered the process :) Read more

Helped cycle my tank quickly! Read more

Pure ammonia. Does a great job in cycling an aquarium. Read more

This is a solid product that is good for setting a good baseline with initial ammonia ppm combined with starter bacteria to tell when and how fast the nitrogen cycle is happening. I personally dosed the initial two PPM of Dr Tim’s and then dosed stability for a week as recommended. After a week ammonia was gone and nitrites were at 2PPM. Week after that my nitrates started dropping and I repeated doses of Dr Tim’s once below the 2 PPM of ammonia and nitrites until both measured zero within 24 hours, that took another week and a half. I’m using a Fluval fx4 with Seachem matrix for media and purigen along with a sponge filter filled with Seachem matrix. Read more
