3 Way Test Strips

3 way test strips provide a quick and easy way to check the free chlorine/bromine/oxygen levels, pH balance and total alkalinity level in your swimming pool water. Simply wave the test strip in the pool water for 5 seconds and then compare with the colour chart on the pack after a further 15 seconds. Use the strips on a regular basis to check for slight imbalances and rectify before things get out of hand.
