DrTim’s Aquatics Ammonium Chloride Solution – 4 oz – for Fishless Cycling in Freshwater & Saltwater Aquariums – Treats 200 Gallons

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 cyclingGreat 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.

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.

Helped me test and cycle my tank quickly. Very easy to use and simple directions/guidelines for use.

Great product to cycle your new aquarium.

wonderful product. does as described.

It is seems like ok. Delivered in time. Didn’t use it yet.

Ammonia to cycle an aquarium works perfect if you follow the instructions

A reasonably priced bottle for peace of mind and simple cycling. Tank cycled within three ish weeks with it. Would recommend using other sources, however, when determining how and with how much ammonia to cycke with.
