API Ammonia Aquarium Test Strips

Each strip is a single-use paper test designed to detect dissolved ammonia in aquarium or pond water. The strip is dipped directly into the tank with no separate vial, reagent drops, or mixing required. After a short wait, the reacted color on the pad is compared against a printed color-coded chart to read an ammonia concentration between 0 and 6 ppm. The pack includes a moisture-resistant tube with a snap-tight cap to help keep unused strips dry between uses, along with guidance on how to respond if a reading shows unsafe ammonia. The strips work in both fresh and saltwater setups, making them suitable for community, planted, or marine aquariums. Regular use as part of a routine testing schedule helps track a tank's nitrogen cycle and catch rising ammonia before it becomes a problem for fish.
