Lifegard saltwater teststrips
To measure pH using Saltwater Lifeguard teststrips, dip one strip into your sample for 2–3 seconds. Remove it and hold it level without shaking off the water. Wait about 15 seconds for the colours to appear on the strip. Look at the colour section marked for pH and compare it to the pH colour chart provided on the bottle or packaging. Match the colour to find out the pH level of your water. This quick method helps check if your saltwater is too acidic, too basic, or balanced for healthy aquatic life.
