API Quick Test Strips 5 in 1 4pk

API Quick Test Strips 5 in 1 (4 pack) let you quickly check pH, nitrite, nitrate, carbonate hardness (KH) and general hardness (GH) in freshwater and saltwater aquariums. Just dip a strip and compare it to the colour-coded chart to see if your water is safe or needs adjusting.

Why Test Your Aquarium Water

For fish to thrive, aquarium water must be similar to that found in their natural environment. Poor water quality can cause fish stress, illness and even death. Regular testing helps you spot problems early and follow the recommendations to treat the water.

Features

• Tests five key parameters: pH, nitrite (NO2), nitrate (NO3), carbonate hardness (KH) and general hardness (GH)
• Suitable for freshwater and saltwater aquariums
• Simple dip-and-read strips with a colour-coded chart
• Pack of 4 test strips

Directions for Use

1. Dip the strip directly into the aquarium and swirl two times.
2. Remove horizontally with pads facing up. Do not shake off excess water.
3. Compare to the colour chart. Starting with the pad closest to your hand, immediately read General Hardness (GH) and Carbonate Hardness (KH).
4. Wait 30 seconds, then read pH, Nitrite and Nitrate.

Keep wet fingers away from unused strips. Store in a cool, dry place. For best results, read in a well-lit area.
