Tetra Pond Test Kit 5in1
A simple to use dip test for instantly checking water quality.
Simply dip the test strip in the water for a few seconds and then wait a minute for it to change colour. Then just compare the colours to the chart on the pack to get your readings. Tetra recommend testing every 2-3 days in new ponds and once a week in established ponds.
Always read the instructions before use.
