CCH2O – ADD BACK KIT

The Add Back Kit (ABK) provides a simple approach to adding concentrated fertilizers or pH adjustors directly into your Under Current® system.

The Add Back Kit utilizes a patented Mazzei injector to pull concentrates directly into the system’s solution. The Add Back Kit uses the Under Current® system’s existing water pump and flow to naturally draw nutrient into the system via venturi action.

Safe and simple.
