Review: Great for Beginner Aquarists looking to cycle their tank! - 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.
Review: Very good for fishless cycling - 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

## Questions & Answers

**Q: will the packaging leak while it's shipping?**
A: Mine leaked and was almost half empty upon arrival

**Q: Is it a dropper bottle**
A: No, however they do provide a plastic dropper that works really good

**Q: How often should i use this? everyday? i've read that adding too much ammonia at one time can actually prolong cycling time so i just want to be sure.**
A: Use a liquid testing kit for ammonia daily when using this product. I kept my ammonia levels at about 2 or 3 ppm. Once the ammonia starts to decrease, test for nitrites. Keep ammonia around 2ppm until nitrates appear. Once nitrates appear, you should be pretty much done.

**Q: How many ounces is this?  Nothing in description on volume.  Dr. Tim's sells 2oz. and 4oz.**
A: I received 2 ounces when I ordered it.

### ⭐⭐⭐⭐⭐ Top quality for fishless cycling :)
*by J***E on September 6, 2025*

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 :)
