Dr. Tim’s Ammonium Chloride – Fishless Cycling Solution – 2 oz
Start your aquarium right with reagent-grade ammonium chloride formulated specifically for fishless cycling. Use it to feed live bacteria and safely convert ammonia to nitrite and nitrate—especially effective when paired with One & Only – Saltwater. 🧪
🔄 How to Use
Carefully dose 4 drops per gallon of aquarium water to reach approximately 2 ppm ammonia–nitrogen. For initial cycling, add concurrently with One & Only bacteria. Monitor ammonia and nitrite daily, and follow Dr. Tim’s 5-day fishless cycle guide for consistent results. Do not exceed 5 ppm total ammonia–N.
📏 Dosing Capacity
