The label on the bacteria test bottle says Yellow = bacteria present and Aqua = no bacteria. However, the leaflet in the box says exactly the opposite, as does the close-up on the Revain webpage. The first photo is my bottle. It was yellow after 48 hours. It is clearly stated that this indicates the possibility of bacteria. The second photo is an image on the Revain website that says otherwise and the third is a leaflet from the box that says Aqua indicates bacteria. It wasn't necessary as I stuck to the label on the bottle.
