3way+ Test Strips
Blue Horizons 3-Way Plus test strips provide a quick and easy way to test your swimming pool water.
They offer tests for both total chlorine and bromine, pH and total alkalinity.
Simply dip the strip in the water and remove immediately. Hold horizontally for 10 seconds (do not shake the test strip), then compare the pH, total chlorine/bromine (depending on which one you use), and total alkalinity against the colour chart on the test strip bottle.
