8oz Ammonium Chloride Solution for Fishless Cycling – Dr. Tim’s Aquatics

Product details

8oz Ammonium Chloride Solution for Fishless Cycling – Dr. Tim's Aquatics is a reagent-grade ammonium chloride solution made specifically to support fishless aquarium cycling. Instead of adding fish, you dose ammonium to provide an ammonia source while your nitrifying bacteria establish themselves. This product is designed to be used alongside nitrifying bacteria, helping you move through the cycle in a controlled way before introducing livestock. The bottle provides total ammonia-nitrogen (TAN) for dosing, and the included instructions outline a typical fishless cycling schedule (often with multiple ammonium additions).

Features:

• Reagent grade ammonium chloride formulated for fishless cycling
• Provides an ammonia source measured as total ammonia-nitrogen (TAN)
• Designed to be used with Dr. Tim’s One and Only nitrifying bacteria
• Simple drop-based dosing guidance for aquarium volume
• Helps you cycle a tank before adding fish, supporting a more predictable start

Specifications:

• TAN concentration: 40 mg/ml of total ammonia-nitrogen (TAN)
• Recommended dose: 4 drops per gallon of aquarium water
