API 5-in-1 Test Strips

Monitors levels of pH, nitrite, nitrate carbonate and general water hardness in freshwater and saltwater aquariums.

Keep your fish healthy and thriving by testing your aquarium water regularly with easy-to-use API 5-in-1 TEST STRIPS. API 5-in-1 TEST STRIPS for freshwater and saltwater aquarium help fish owners measure levels of Nitrite, Nitrate, Carbonate & General Hardness, and pH found in aquarium water. In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even death. Just dip a strip directly into your aquarium and use the color-coded chart to determine if your water is safe, or if adjustments are needed. Then follow the recommendations to treat the water – it’s that simple.

Instructions for use:
Dip strip directly into aquarium and swirl two times. Remove horizontally with pads facing up. Do not shake off excess water. Compare to the color chart on the tube. Starting with the pad closest to your hand, immediately read General Hardness (GH) and Carbonate Hardness (KH). Wait 30 seconds, then read pH, Nitrite, and Nitrate. Keep wet fingers out of tube. Close tube tightly after removing strip. Store in a cool, dry place. For best results, read in a well-lit area.
