API Ammonia Aquarium Test Strips
Ammonia in an aquarium can come from several sources including fish waste, uneaten food, and other decaying matter. Ammonia is very harmful to fish.

Great product for beginners. I didn’t know how dangerous ammonia could be until I started using these strips. Now I test weekly and keep my tank stable.
