API 5 In 1 Aquarium Test Strips

Sold out

These test strips are designed to measure pH, nitrite, nitrate, carbonate hardness, and general hardness in a single dip, giving a quick snapshot of overall water quality. Each strip is coated with reagent pads that change color on contact with aquarium water, and results are read by comparing the strip to a printed color chart included with the product. The format works for both freshwater and saltwater setups, making it a flexible option for community tanks, planted tanks, or marine systems. No separate test tubes, liquid reagents, or measuring are required, so results are available within moments of dipping the strip. Packaging is designed to keep strips dry and effective until use, since moisture can degrade the reagent pads over time. A leaflet explaining how to interpret each color result and address out-of-range readings is included. Regular use is intended to help fishkeepers catch shifts in water chemistry before they become stressful or harmful to aquatic life.
