I tried bac bombs , biological enhancers and all sorts if other stuff whilst emergency cycling with a sick fish .. no2 n 3 n amonia just would not level fast enough . 1 bottle of dr Tims all at once levelled amonia a d no2 to 0 so fast i was amazed they didnt go back up either(make sure you watch the how to use video by dr tim on Youtube). Best stuff ever, will always have a bottle ready to in case of an emergency

I cycled a 40 gallon breeder tank using Dr. Tims Nitrifying solution along with his ammonia product. The tank completely cycled in five days as verified with the API master test kit. This is a great product! The fish are thriving in their new home.

It didn't start working on few first days until after doing a little bit of research that I realized I needed some nutrients in my tank to provide enough energy for the bacteria to reproduce. The problem is my case was lack of enough phosphorus and magnesium in water. So, check your local water for traces of these elements if your fishless cycle has stuck and then add pinch of ground fish food into your tank in case of lacking of them in your fish tank water. Check your fish food to make sure it has these two before doing so. If you need more information, search for fishless cycle phosphate block and you'll find more information on this.
