Keep your freshwater fish tank in balance with the Aquila Aquarium Water Test Strips 7 in 1 Kit. Each pack includes 150 test strips, a test tube, and a thermometer, giving you everything you need to monitor your aquarium's water quality with ease. These comprehensive strips test 7 critical water parameters in one simple dip: pH, Total Alkalinity, Hardness, Chlorine, Nitrate, Nitrite, and Ammonia Nitrogen — helping you catch imbalances before they affect your fish. Suitable for freshwater fish tanks and fish ponds alike, these strips deliver fast, reliable results in seconds. For best results, keep your hands dry before handling the strips, avoid touching the test areas with your fingers, and read results under natural light. Always cover and tighten the bottle cap after each use, and store in a cool, dry place away from humidity. Do not remove the desiccant packets inside the bottle. With 150 strips per pack, you'll have plenty on hand for regular monitoring to keep your aquatic environment healthy and thriving.
