24OZ HYDROFEED FERTILIZER INJECTOR It comes with chemical-resistant seals24 OZ HYDROFEED FERTILIZER INJECTOR HydroFeed works differently than a standard hose end sprayer. A standard hose end sprayer pulls the chemical up and out, emptying the tank. HydroFeed adds water back into the tank as your chemical is being pulled out. Because your chemical has a higher density than water, it sits on the bottom of the tank. Our outlet tube reaches the bottom of the tank so when clean water is being added to the tank, it stays on top
