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.

Product Questions

What is the typical shelf life once the product has been opened?
Question by: Peter L on Nov 9, 2022, 10:31 AM
Thanks for reaching out to us! It should still last 8 months even if opened, just monitor the odor to ensure it doesn't start to smell like sulphur as you near the 8 month mark. Please let us know if we can help with anything else!
