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
  • Rich in minerals, trace elements, polysaccharides, and vitamins
  • Excellent source of vitamin B12
  • Flash pasteurized at peak fermentation (not a live product)
  • Can also be used to gutload live foods


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.
