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 ### ⭐⭐⭐⭐⭐ Quickest way to cycle your tank. *by L***A on 16 November 2025* ### ⭐⭐⭐⭐⭐ Easy to use and dependable. *by T***H on 19 March 2025* ### ⭐⭐⭐⭐⭐ If you are new to aquarium keeping I can recommend cycling your tank using this rather than fish *by S***R on 6 December 2023* ## 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.pt/products/307081708-drtim-s-aquatics-ammonium-chloride-solution-4-oz-for-fishless](https://www.desertcart.pt/products/307081708-drtim-s-aquatics-ammonium-chloride-solution-4-oz-for-fishless) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
