✅ Tests 7 parameters in one strip: Simultaneously checks water hardness, nitrate, free chlorine, total chlorine, total alkalinity, carbonate, and pH. Saves time, no need for multiple separate tests.

✅ Quick to use: Dip in water for 2 seconds, lift, lay flat, then wait 60 seconds. Compare colors with the chart on the bottle. Even beginners can use it without specialized knowledge.

✅ 100 strips, long-lasting: Each bottle contains 100 strips, suitable for weekly testing or during water changes. Helps maintain continuous water quality more conveniently.

✅ High-quality paper material: Test strips absorb water evenly, colors develop clearly, easy to read results. Reduces color distortion issues from general use. Proper storage helps maintain consistent test results.

✅ Suitable for various freshwater aquariums: Can be used for ornamental fish tanks, betta tanks, freshwater shrimp tanks, fish ponds, and initial tap water testing. Not recommended for saltwater aquariums.

🔥 Helps solve common problems: Clear water may look clean, but water parameters might be unbalanced. Test strips help quickly identify if chlorine, nitrate, or pH are out of range, allowing for timely water adjustments before affecting fish.

Reference ranges for freshwater:

• Nitrate: Less than 50 mg/L
• Nitrite: Less than 1 mg/L
• Free Chlorine/Total Chlorine: 0 mg/L
• Water Hardness (GH): 25-150 mg/L
• Total Alkalinity: 40-120 mg/L
• Carbonate: 40-120 mg/L
• pH: 6.8-7.6

How to use: Dip the test strip into aquarium water for 2 seconds. Lift it out and gently shake off excess water. Lay the strip flat, wait 60 seconds, then compare the colors with the chart on the bottle in natural light.

Appropriate uses:

• Check water parameters after a water change to see if chlorine or pH has changed.
• Test water before adding new fish to the tank, reducing the risk of unstable water.
• Use for betta tanks or freshwater shrimp tanks that require relatively stable water parameters.
• Test pond water after rain or after refilling to monitor water changes.

💡 Suitable for regular maintenance: Regular fish keepers can use it weekly or immediately when fish appear lethargic, swim abnormally, or have a poor appetite, to quickly identify causes related to water quality.

Precautions: Avoid direct contact with test pads. Close the bottle cap immediately after use. Store away from moisture and light. Compare colors in natural light. Should be used within 3-6 months after opening. If unopened, shelf life is approximately 2 years.

Usage tip: For consistent readings, test at similar times each week and use water samples from the same spot in the tank. This makes it easier to compare changes.
