What you need to do:

• Use a clean bottle to collect water sample.
• Allow 2 days after shock dosing your pool before taking water sample.
• Rinse bottle with water from your pool before collecting the sample.
• Fill the bottle with pool water away from any return fittings at a depth of half a metre.
• Fill bottle to overflowing so there is no air space and then cap.
• Do not leave sample in direct sunlight and ensure sample is fresh for testing (ideally 1 hour).
• Do not allow sample to get too warm.
• Record pool volume. If unsure of pool volume, measure length (m) x width (m) x average depth (m) x 1000 = volume in litres.
