Support a diverse, biologically active aquarium with Hydrospace PNS ProBio, a live culture of purple non-sulfur bacteria (PNSB) for marine, reef and freshwater aquarium systems.

PNS ProBio contains live Rhodopseudomonas palustris, a highly versatile beneficial microorganism that can utilize organic compounds while contributing to the aquarium's microbial food web. It provides reef keepers with a different approach to microbial diversity than traditional nitrifying bacteria products used primarily for cycling.

PNS bacteria can become part of the aquarium food web while helping process organic material, making PNS ProBio a versatile addition to established reefs, freshwater systems, large displays and professionally maintained aquariums.

Available in 16 oz for typical home aquarium use and a value-sized 1 gallon option for large systems, fish rooms, maintenance professionals and frequent dosing.
