PNS ProBio is a live Purple Non-Sulfur bacteria supplement that offers a host of benefits to both saltwater and freshwater aquarium systems alike. In addition to its ability to naturally remove ammonia, nitrite, nitrate, and phosphate via assimilation and denitrification; ProBio is also able to break down organic waste and detritus to keep your system running efficiently. The strain of PNS contained in ProBio (Rhodopseudomonas palustris) has been known to compete aggressively with pathogens such as Vibrio and can even outcompete algae and cyanobacteria for vital resources, so dose it regularly to keep your aquarium in balance.

In addition to its powerful biofiltration capabilities, ProBio can also serve as a nutritious addition to your livestock's diet. It is rich in protein, carotenoids, and vitamins and selectively consumed by corals, where it can often carry out symbiotic interactions with zooxanthellae. For herbivorous fish, you can use ProBio as a prebiotic and use it to soak food to help break down cellulose and ease digestion.

ProBio has been designed to be used regularly as part of a routine feeding and maintenance regimen. It is also great for reestablishing beneficial bacterial colonies after medications or to address "old tank syndrome". Each sealed bottle has a shelf life of 8 months and can tolerate temperature swings from 33°F to 130°F.

Natural, nutrient-dense marine snow replacement

  • Food for corals and other filter-feeding invertebrates
  • Simulated marine snow made with natural chitin base
  • Photofermented with live purple non-sulfur bacteria

PNS YelloSno is photofermented with live Rhodopseudomonas palustris bacteria, which is found naturally in marine habitats, marine snow, and inside the guts of wild corals. This purple non-sulfur bacteria (PNSB) is extremely nutritious, highly-digestible coral food with a crude protein content of 72-74% and high levels of beneficial stearic and oleic fatty acids. The growth medium for the R. palustris bacteria in YelloSno is a natural source of chitin, which is rich in minerals, trace elements, polysaccharides, and B vitamins such as B12. 


YelloSno can also be used to gutload live zooplankton foods to increase the nutritional profiles of adult brine shrimp, amphipods, daphnia, and more. 


Instructions for Use

  • Use just after lights-out
  • Remove mechanical filter media
  • Turn off protein skimmer
  • Shake bottle lightly before use
