Dr Tim’s Ammonia Solution for Fishless Cycle
Ammonium Chloride for fishless cycling. As the term implies, fishless cycling means without fish, but there needs to be a source of ammonia for the nitrifying bacteria. That’s why we provide ammonium chloride drops (dose 4 drops per gallon of aquarium water, 100 drops = 5 ml = 1 teaspoon) – for you to use to feed the nitrifying bacteria that come in our One & Only Live Nitrifying Bacteria.
Available in 2 sizes: 2oz & 4oz

I used this solution to start my fishless cycle and it worked perfectly. The instructions were clear and the ammonia level rose steadily. My bacteria colony established within two weeks. Highly recommended for beginners.

The product arrived on time and the dosage is easy to measure. I added it to my tank as directed and saw visible progress in the nitrifying bacteria growth. A reliable tool for cycling.

This was exactly what I needed for my first aquarium cycle. The 4-drop-per-gallon rule made it simple to follow. My tank is now fully cycled and ready for fish.
