Fast ammonia detection in water to ensure safe water quality; ideal for aquariums, hydroponics, wastewater, and education. Measure 0-100 ppm NH3/NH4+ in seconds compared to lab methods.

Indigo® Instruments 0-100 ppm Ammonia Test Strips provide a quick, practical way to monitor ammonia and ammonium (NH3/NH4+) levels in water where immediate feedback is needed. Used by aquarium keepers, hydroponic growers, wastewater technicians, and educators, these test strips support routine monitoring, trend tracking, and field verification of nitrogen compounds that can affect aquatic life, plant systems, and water processes. Each strip delivers a clear, color-matched result in less than 60 seconds with no reagents, meters, or glassware required, making them a convenient tool for day-to-day decision-making alongside more detailed laboratory methods.

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 ion (NH4+) and how pH influences this balance. Learn about colorimetric detection methods and the chemistry of ammonia indicators.
Biology Explain ammonia’s role in the nitrogen cycle and its impact on aquatic organisms. Recognize how biological nitrification converts ammonia to nitrite and nitrate in ecosystems and wastewater treatment.
Environmental Science Relate ammonia testing to water quality monitoring, eutrophication, and pollution control. Interpret test results to assess ecosystem health and the effectiveness of treatment or remediation systems.
Engineering / Applied Technology Apply ammonia test data for process optimization in wastewater treatment, aquaculture, and cooling systems. Understand how ammonia levels influence corrosion, biofilm growth, and overall system efficiency.

When to Use Lab Testing vs Test Strips

  • Routine Monitoring: Use ammonia test strips for daily or weekly checks in aquariums, hydroponic systems, or wastewater basins. Quick detection prevents buildup before it becomes toxic.
  • Process Validation: When commissioning new filtration, biological treatment, or feed dosing systems, test strips provide immediate feedback for on-site adjustments.
  • Regulatory Compliance: If local or industry standards require documented ammonia levels (e.g., NPDES, ISO 14001), confirm results using a calibrated laboratory instrument.
  • Research or Calibration: Use test strips to screen multiple samples; send selected results for lab verification to maintain data integrity and long-term trend reliability.

Field test strips are ideal for routine checks; when results approach regulatory limits or show unexpected variation, confirm with a calibrated instrument.
