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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by A***A on 6 January 2026* Worked great to start up a fish tank ### ⭐⭐⭐⭐⭐ Quickest way to cycle your tank. *by L***A on 16 November 2025* Used this to cycle my fish tank. Worked well and took all the guesswork out of the process. ### ⭐⭐⭐⭐⭐ Great - here’s why... *by K***I on 5 September 2018* So when I bought my 54 gallon aquarium... I did not know much. I was told at the LFS to buy this API quick start (good product) and some stress cost stuff and all good start adding fish... so I setup this tank and put the API quick start in and planted plants - one melted and the others did well but 3 days later my tank had a chalky appearance. So I took the filtering system apart EHEIM ( great product) washed the pre-filter and everything cleared. Perhaps it was the rotting plant? Needless to say I had to take the tank down and reset it up at home- same thing chalky after 3 days. So what I learned is that is a bacterial bloom but i provided no fish and no ammonia (fish excrement). So basically the bacteria bloomed and died. Ok I got this now. So did a 50% water change and started over again after receiving the DR Tim’s Ammonia Chloride. Put in API Quick start again and now added 216 drops of ammonium chloride- tested in the morning after. Ammonia was NOW at 4ppm. That evening tested and had a twinge of nitrite - just a barely there. Next morning tested and ammonia about 3ppm and definitely at .50 nitrite. Tested that evening now at 3ppm ammonia and 2.0 ppm nitrite - tested nitrate just a smidge. This thing is just rocking and rolling along in days!!! Only days !!! Following the exact path line! Wish I knew then what I know now - don’t use raw fish or raw shrimp or a bunch of fish food to generate ammonia - get a good product for starting quick with bacteria and this ammonia AN you’re set! This sooo speeds up the process!!! I’ll keep updating... UPDATE: next day: ok now ammonia is at 2ppm; nitrites at 2.00ppm; and nitrates SMIDGE... between 0ppm and 5.00 ppm. Plants in tank are thriving NOW! UPDATE 4 days in: Ammonia 2 ppm down from 4ppm Nitrites 5ppm up from 2ppm Nitrates now 10ppm up from trace 5 days - ammonia 1 ppm (when it gets down to about .50 I’m gonna have to add some more in) - nitrites 5 ppm - nitrates 20 ppm now 6 days Ammonia at ZERO - gotta add a full dose again. Nitrites 2 ppm Nitrates looks like 2 ppm a teensy bit darker but only a smidge - Nitrates going down? WELL water is crystal sparkling but apparently I have to add more ammonia....so gonna do it Plants looking REALLY good - I wonder if the plants are taking care of some of the nitrates? Tested Ammonia after 6 hours after putting it in and ammonia is back up at 4ppm 7 days Ammonia BACK DOWN to only .25 ppm! Nitrites at 2 ppm Nitrate at 5 ppm <- I believe the aquatic plants are using up the nitrates! And keeping it in check. 8 days Ammonia 0 ppm (adding another 1/2 dose 2 drops per gallon approximately 106 drops) Nitrites 2 ppm Nitrates 2 ppm ## Frequently Bought Together - DrTim’s Aquatics Ammonium Chloride Solution for Fishless Cycling - 4 oz., Treats 200 gal. – Fish Tank Cleaner for Saltwater, Freshwater & Reef Aquariums - API FRESHWATER MASTER TEST KIT 800-Test Freshwater Aquarium Water Master Test Kit, White, Single, Multi-colored - Dr.Tim’s Aquatics Freshwater One & Only Nitrifying Bacteria – For New Fish Tanks, Aquariums, Water Filtering, Disease Treatment – Eco-Friendly Fish Tank Cleaner – Removes Toxins – Treats 30 Gallons --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/307081708-drtim-s-aquatics-ammonium-chloride-solution-4-oz-for-fishless](https://www.desertcart.no/products/307081708-drtim-s-aquatics-ammonium-chloride-solution-4-oz-for-fishless) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
