API pH Test Kit For Freshwater Fish Aquarium

API Freshwater pH Test Kits For Fish Aquarium Is A Quick And Easy Way To Monitor pH Levels To Maintain Healthy Freshwater Conditions
  • The pH test kit monitors pH to maintain healthy freshwater conditions in your tank
  • pH control is vital to prevent the harmful effects of excessively alkaline or acidic aquarium water on fish and plant life
  • Fish require a specific pH level to be happy and healthy
  • pH in an aquarium can change due to fish waste, the addition of tap water and the build-up of natural acids
  • This kit will keep pH levels in check 
  • Tests read pH from 6.0 – 7.6
  • The test results help you quickly and easily determine whether your levels are optimal for your fish

Pack includes:

  • 250 tests
  • 1 test bottle
  • Instructions
  • Glass test tube
  • Colour chart

Why Test pH?

  • pH is the measure of the acidity of water
  • A pH reading of 7.0 is neutral, a pH higher than 7.0 is alkaline, and a pH lower than 7.0 is acidic
  • Maintaining the aquarium at the proper pH ensures optimal water quality 
  • The pH should be tested weekly since neutral materials in the aquarium (such as fish waste and uneaten food) can cause pH changes


  • It is recommended that you take a few minutes each week to monitor your aquarium conditions and create a better underwater world for your fish

Testing Tips

  • The minimum pH reading for this kit is 6.0 and the maximum is 7.6
  • Under extreme water conditions, readings below the minimum will read 6.0 and above the maximum will read 7.6
  • pH adjustments outside the range of this kit will not show any changes until the pH of the water is within the range of this kit 
  • When keeping livebearers, goldfish, African Cichlids or marine fish and invertebrates, use the API HIGH RANGE pH TEST KIT

Direction for Use

  1. Fill a clean test tube with 5mL of water to be tested (to the line on the tube)
  2. Add 3 drops of pH Test Solution, holding the 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 the solution 
  4. Read the test results by comparing the colour of the solution to the pH Colour 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

Recommended pH levels

  • A pH of 7.0 is ideal when keeping a community aquarium containing a variety of tropical fish 
  • Goldfish and livebearers prefer a pH of 7.5
  • Many Amazonian fish, like angelfish and neon tetras, prefer a pH of 6.5 - 6.8
  • Mollies and swordtails thrive at pH 7.2 - 7.5
  • To raise or lower the pH of a freshwater aquarium, use API pH Up or pH Down
  • To automatically adjust pH to a preset level, use API PROPER pH 6.5, 7.0 or 7.5
