Prodibio additives are uniquely packaged in small sealed single-dose glass vials. These vials are tinted to protect the active ingredients in our products from light and allow for a long shelf life and storage at room temperatures. The vials contain very little water and are pre-measured for single use. We carry all the most popular Prodibio products (BioDigest, Bioptim, Reef Booster), as well as several of the less popular Prodibio offerings.
