6-in-1 Aquarium Test Strips – Fast, Accurate Water Testing (100 Strips)

These 6-in-1 test strips provide a quick, reliable snapshot of aquarium water quality to help detect issues before they harm fish or plants. Each strip measures six essential parameters: Nitrate, Nitrite, Chlorine, Total Hardness (GH), Carbonate Hardness (KH), and pH. To use, immerse a strip for 2 seconds, remove and lay flat, then wait 15 to 60 seconds to match the colors against the chart on the bottle. Ideal for both beginners and experienced aquarists to maintain a stable tank environment.
