PNS CryoPak

The Frozen Aquarium Food that Adds Live Probiotics

Less residual wastewater—Less odor.

 

Fresh & Cencentrated

 

Purple nonsulfur bacteria (PNSB) are increasingly valued for their nutritional and probiotic properties when used as a live microfood or feed additive for diverse fish and invertebrate species. While conventional bottled PNSB-based products generally exhibit good shelf stability, there are many applications where a frozen concentrate offers distinct advantages.

​

PNS CryoPak™ is a professional-grade frozen PNSB formulation produced from active cultures using a carefully controlled centrifugation process. By removing excess liquid prior to freezing, this unique product delivers exceptionally high cell density in a compact, convenient format that is ideal for aquariums, ponds, and live feed production vessels.

​

The concentrated, living biomass in PNS CryoPak™ is preserved at freezing temperatures to maintain culture viability and nutritional integrity. Its unique “ice pop” packaging is engineered for ease of use and efficient freezer storage.

​

Directions

Keep frozen until use. Package treats up to 1,600 gallons. To broadcast feed, simply add frozen portion directly to aquarium/culture vessel. Suggested maximum dosage is 12.5 mL/40 gal/day. Each 1-inch section of ice pop treats ~40 gallons.

​
