The multi-purpose Peta dispenser can be used for liquids or dissolved salts and solids. That is, it can be used as a 24-hour bloat dispenser, and also as a zinc (non-facial-eczema mineral supplements) and other elements dispenser. The 48-hours dispenser means fewer trips to the trough which is especially helpful for dry-stock or run-off use. The Bead-Jet technology provides constant dilution of mineral or additive over a 48hr period. The dispenser adjusts its flow to match the draw-off of stock water. The trough water is still left at working strength on the 3rd day. This means in many cases re-loading of the dispenser is not required until the morning of the 4th day. Full instructions supplied.
