Comprehensive 5-Way Analysis

Don't let the small pack fool you; these strips provide the same high-accuracy diagnostics as the professional kits. Each strip monitors:

• pH: Helps prevent fluctuations that cause fish stress.

• Nitrate ($NO_3^-$): Indicates when a water change is overdue.

• Carbonate Hardness (KH): Protects against sudden pH crashes.

• General Hardness (GH): Ensures proper mineral levels for fish vitality.

Perfect For:

• New Tank Owners: Great for monitoring the initial "cycling" process of a new aquarium.

• Emergency Situations: If your fish are acting strangely, get answers instantly.

• Quarantine & Travel: Easily test temporary tanks or water used for transporting new fish.

• Trialing API Quality: Experience why API is the #1 name in water care before upgrading to the 25-count or 100-count packs.

1. Dip the strip into the tank for 2 seconds.

2. Wait for 30–60 seconds for the pads to react.

3. Compare to the color chart provided on the packaging for an immediate diagnosis.
