Worked well and took all the guesswork out of the process. Review: 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 ## Features - Item Category: Aquarium Pond Water Treatment - Item Trademark: Dr Tim's Aquatics - manufacturer: Dr Tim's Aquatics ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00WSNYRDS | | Allergen Information | Almonds Free | | Best Sellers Rank | #25,485 in Pet Supplies ( See Top 100 in Pet Supplies ) #172 in Fish Medication & Health Supplies | | Brand Name | DrTim's Aquatics | | Customer Reviews | 4.6 4.6 out of 5 stars (3,596) | | Global Trade Identification Number | 00812540018311 | | Included Components | DrTim's Aquatics Ammonium Chloride - 4 oz bottle | | Item Form | Liquid | | Item Type Name | Aquatics Ammonium Chloride Water Treatment | | Item Weight | 2 Ounces | | Liquid Volume | 4 Fluid Ounces | | Manufacturer | DrTim's Aquatics, LLC | | Manufacturer Part Number | 831 | | Model Number | 831 | | Target Species | Fish | | UPC | 812540018311 | | Unit Count | 4 Milliliters | ## Product Details - **Brand:** DrTim's Aquatics - **Item form:** Liquid - **Item weight:** 2 Ounces - **Liquid volume:** 4 Fluid Ounces - **Unit count:** 4 Milliliters ## Images ![DrTim’s Aquatics Ammonium Chloride Solution – 4 oz – for Fishless Cycling in Freshwater & Saltwater Aquariums – Treats 200 Gallons - Image 1](https://m.media-amazon.com/images/I/61xRAuB3eIL.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by L***A on 16 November 2025* Used this to cycle my fish tank.

Sure you can go buy a litre of ammonia from the shop but then you need to do a little math to figure out the correct dose for the concentration your bottle contains. Then you have more ammonia then you will probably ever need for the remainder of your natural life. But with doctor Tim’s they have to all figured out for you and it’s consistent and repeatable as long as you can follow directions. The hardest part is waiting for your ammonia and nitrite levels to come down as your tank cycles. Combine this with Fritz 7 or turbo start and you have a fast lane to a cycled tank. ## 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.tw/products/307081708-drtim-s-aquatics-ammonium-chloride-solution-4-oz-for-fishless](https://www.desertcart.tw/products/307081708-drtim-s-aquatics-ammonium-chloride-solution-4-oz-for-fishless) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-21*
