Simple One-Button Operation: Get reliable results in minutes with intuitive push-button testing
Portable Design: Compact, battery-powered unit for on-site testing anywhere
Cost-Effective: Reusable colorimeter reduces long-term testing costs compared to disposable strips
Complete Kit: Includes everything needed to start testing immediately
Professional Grade: Trusted by aquarists, pond keepers, and aquaculture professionals worldwide
Why Ammonia Testing is CriticalAmmonia (NH₃) is one of the most toxic substances in freshwater systems, produced by fish waste, uneaten food, and decaying organic matter. Even low concentrations cause stress, gill damage, immune suppression, and death in fish and invertebrates. Regular ammonia monitoring is essential for:
New tank cycling and establishing beneficial bacteria
Detecting filter failures or biological imbalances
Preventing fish stress and disease outbreaks
Optimizing feeding and stocking levels
Troubleshooting water quality problems
ApplicationsFreshwater Aquariums: Monitor ammonia during cycling, after water changes, when adding new fish, or troubleshooting fish health issues. Essential for tropical, goldfish, and planted tanks.Koi & Ornamental Ponds: Track ammonia levels in outdoor ponds, especially during spring startup, after heavy feeding, or following medication treatments.Freshwater Aquaculture: Ensure optimal water quality in tilapia, catfish, trout, and other freshwater fish farming operations to maximize growth and survival rates.Hatcheries & Breeding: Maintain pristine water conditions for sensitive fry and breeding stock.Technical Specifications
