The SeaChem HydroTote is a collapsible jug that holds up to 5 gallons (20 Liters). It`s perfect for customers that get their saltwater, RO water, or DI water at their local fish store. When not in use, it easily folds up to take up less space. It pours easily and can withstand a drop of up to 9 feet while full. HydroTote is the ideal space-saving alternative for 5 gallon hard jugs that simply consume too much space.
