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

DrTim’s Aquatics Ammonium Chloride Solution has been a game-changer in setting up my new aquarium. This reagent-grade solution simplifies the fishless cycling process by providing a precise ammonia source, eliminating the need for guesswork. When used in conjunction with DrTim’s One & Only Live Nitrifying Bacteria, I was able to establish a healthy biofilter in my tank without subjecting any fish to harmful ammonia or nitrite spikes. The easy-to-dose liquid formula treats up to 400 gallons, making it both efficient and cost-effective. I highly recommend this product to both novice and experienced aquarists aiming for a safe and effective aquarium setup

This stuff helped cycle my tank pretty quick. I was using it with Seachem Stability and saw nitrites show up in just a couple days, which was way faster than I expected. It’s a clean ammonia source and didn’t cloud the water or mess with the pH. Only issue I had was with the dosing—it says 4 drops per gallon but the cap has different markings and it’s not super clear how much to use if you need to redose. I ended up just testing a lot and going by that. Still, it did exactly what I needed it to do and I’d use it again, just wish the instructions were laid out better.
