What is pH ? pH is an abbreviation for Potential Hydrogen it represents the concentration of Hydrogen Ions in a liquid solution. This concentration of Ions determines if water is Acidic, Neutral or Basic (alkaline). The scale of pH is from 0-14. Neutral is defined as 7.0. Acidic pH is under 7.0 and Alkaline and/ or Basic is over 7.0.
Why analyse pH ? The pH of water is one of the most important parameters to measure because numerous biological processes depend on pH. The pH plays an important role in the blood systems of aquatic organisms. Broad fluctuations can severely affect them. It is recommended to test the water weekly at different times in order to chart changes that can affect the well being of the aquarium inhabitants. Always test pH before adding fish. The pH also affects the toxicity of ammonia present in the aquatic habitat. When the pH is high, the concentration of toxic (NH3) 3is greater. When pH is below 7.0 most of the ammonia is in a non-toxic form (NH4+). The amount of toxic ammonia increases dramatically when the pH is over 8.0.

Instructions
1. Fill test tube to the 5ml line with water to be tested.
2. Add 3 drops of reagent into test tube. Insert cap hold with finger and shake well to mix. Attention! always use the cap, Avoid skin contact.
3. Immediately match test colour to the closest colour on the chart.
4. After use rinse the tube with fresh tap water to ensure it is clean for next use.
