Monitor aquarium or aquaculture ammonia levels quickly with Indigo® 0-100 ppm test strips. Maintain safe water for fish, shrimp, and aquatic plants. Reliable results in seconds.

Ammonia is one of the most critical water quality parameters in aquarium and aquaculture systems, as elevated levels can quickly stress or harm fish, shrimp, and other aquatic life. Indigo® 0-100 ppm Ammonia Test Strips provide a fast, practical way to monitor ammonia and ammonium (NH3/NH4+) levels in both freshwater and marine environments. Used by home aquarists, shrimp breeders, and commercial hatcheries, these test strips support routine monitoring and early problem detection with clear, color-matched results in seconds; no reagents, meters, or glassware required.

We've been selling ammonia test strips since 2014. Buy fully documented Indigo® ammonia test strips, 25 strips/vial, with a guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd").

Learning Outcomes by Discipline

Discipline Key Learning Outcomes
Chemistry
  • Understand the equilibrium between ammonia (NH3) and ammonium (NH4+) in aqueous systems.
  • Recognize how pH and temperature affect ammonia toxicity and ionization balance.
  • Interpret test strip results in the context of solution chemistry and colorimetry.
Biology
  • Explain the role of nitrifying bacteria in converting ammonia to nitrite and nitrate.
  • Assess the physiological effects of elevated ammonia on fish gill and tissue health.
  • Relate microbial metabolism to water quality stability in aquaculture systems.
Environmental Science
  • Describe the nitrogen cycle as it applies to closed aquatic ecosystems.
  • Evaluate water testing as a sustainability tool in fish farming and hatchery management.
  • Connect routine ammonia monitoring to regulatory compliance and ecosystem protection.

Best Practices

  • Test daily in new or heavily stocked systems.
  • Maintain temperature and pH records; ammonia toxicity increases with both.
  • Ensure biofilters are cycled and oxygen levels adequate for nitrifying bacteria.
  • Cross-check periodically with nitrate test strips to confirm full nitrification.
