Dosing and Fluid Meter System & Dual DOS Reservoir Combo

This is a product that combines a dosing and fluid meter system with a dual dosing (DOS) reservoir. The dosing and fluid meter system accurately measures and dispenses precise amounts of liquids, such as fertilizers, into the aquarium. The dual DOS reservoir holds and stores these liquids for later use. This combo allows for efficient and convenient dosing of liquids in an aquarium setup, helping to maintain a balanced and healthy environment for aquarium inhabitants.
