If it does not bleach out within 30 seconds the ozone generator is no longer effective and requires repair or replacement. This is a single use test kit. ie cannot be re-used (unless the media did not change colour due to no ozone output and can be kept sealed until the subsequent test) Kit contents - test tube, adaptor hoses, instructions.
