API 5-in-1 Test Strips API 5-in-1 Test Strips provide a fast dip-and-read way to check five important aquarium water parameters: pH, nitrite, nitrate, carbonate hardness, and general hardness in freshwater and saltwater aquariums. API 5-in-1 Test Strips for Fast Freshwater and Saltwater Water Checks API 5-in-1 Test Strips are useful for routine aquarium monitoring when you want quick results without liquid reagents or separate test tubes. Regular testing helps catch water-quality changes before they become stressful for fish, plants, corals, or invertebrates. Five-Parameter Aquarium Testing for pH Nitrite Nitrate KH and GH Tests pH, nitrite, nitrate, carbonate hardness, and general hardness. Suitable for freshwater and saltwater aquariums. Dip directly into aquarium water with no separate vial required. Highly precise colour chart helps make results easier to compare. Useful for routine weekly checks and quick troubleshooting. Desiccant-lined tube with snap-tight cap helps protect strips from moisture. Includes information to help correct unsafe water conditions. API 5-in-1 Test Strip Reading and Storage Directions Remove one strip from the tube and close the tube tightly right away. Dip the strip directly into the aquarium and swirl two times. Remove the strip horizontally with pads facing up. Do not shake off excess water. Compare General Hardness and Carbonate Hardness immediately. Wait 30 seconds, then read pH, nitrite, and nitrate. Read results in a well-lit area and keep wet fingers out of the tube. Store the tube tightly closed in a cool, dry place.
