The Prodibio Dose'n Drop Dosage System is a manual dosing kit. It allows users to add products in the aquarium several times throughout the week instead of just once every 15 days to maintain more-constant water parameters. It can be mounted on the aquarium or sump and has adjustable flow rates. It is designed for use with all of the Prodibio Pro products and comes with one vial of BioDigest Pro and one vial of Bioptim Pro.

The Pro versions include: Prodibio BioDigest Pro Freshwater/Saltwater, 10 Vials; Prodibio Reef Booster Pro Saltwater, 10 Vials; and Prodibio Stop Ammo Pro Freshwater/Saltwater, 10 Vials.
