Inquiry (采购产品): Water Coloring I would info on colorants that can be used in domestic water supplies, not just toilets. We are losing water from our tank and network and it could even be that adjoining properties are tied in. We think adding color to the water is the easiest way as long as it is not harmful to the health. **** Hidden Message ***** Brad Larsen 36 S.
