About API pH Test Kit
Maintaining the ideal pH balance within an aquarium ensures optimal water quality and contributes to happy, healthy fish, so the handy API pH Liquid Testing Kit allows regular monitoring so imbalances can be corrected before aquarium inhabitants are affected.
Natural materials, including fish waster and uneaten food, can contribute to pH changes, so the testing kit monitors pH from an acidic minimum of 6.0 to an alkaline maximum of 7.6.
When testing the pH of the aquarium water, it's important to know which pH is appropriate for the species kept within the enclosure, as not all fish thrive at a neutral pH reading of 7.0. Community type fish enjoy a neutral 7.0, goldfish and livebearers prefer a higher pH of 7.5 whereas many Amazonian fish, such as angelfish and neon tetra, thrive at pH levels between 6.5 and 6.8. Mollies and Swordtails will appreciate a pH level of 7.2 to 7.5.
To remove childproof safety cap: With one hand, push red tab left with thumb while unscrewing cap with free hand.
1. Fill a clean test tube with 5 ml of water to be tested (to the line on the tube).
2. Add 3 drops of pH Test Solution, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops.
3. Cap the test tube and invert tube several times to mix solution.
4. Read the test results by comparing the color of the solution to the pH Color Card. The tube should be viewed in a well-lit area against the white area of the card. The closest match indicates the pH of the water sample. Rinse the test tube with clean water after use.
