ARTECIFE PNSB (16oz)

Enhance your aquarium's ecosystem with ARTECIFE PNSB, the ultimate solution for a healthier microbial community. Our improved formula actively removes ammonia, nitrite, and nitrate while breaking down organic waste. It nourishes filter-feeders with essential nutrients and serves as an effective probiotic. Ideal for feeding corals and initiating new setups, ARTECIFE PNSB is your key to a thriving aquatic environment.

Every bottle includes the following bacteria:

  • Rhodopseudomonas palustris (Freshwater or marine, denitrifier, known coral symbiont)
  • Rhodospirillum rubrum (Freshwater or marine, excellent "carbon dosing" exporter)
  • Rhodobacter sphaeroides (Freshwater and marine, strong biofilm builder) 

Description
What does ARTECIFE PNSB do?
Purple nonsulfur bacteria (PNSB) are ancient microorganisms found in environments ranging from terrestrial soils to freshwater and marine sediments. Their remarkable adaptability is showcased through their ability to perform chemoautotrophy, chemoheterotrophy, photoautotrophy, and photoheterotrophy. This versatility allows them to function in roles similar to nitrifying bacteria, heterotrophic bacteria, or even plants/algae, with their most notable and beneficial use as photoheterotrophs.

In conditions where oxygen is scarce, light is available, and organic matter is abundant—often just below the surface layer of aquarium substrates—PNSB thrive. Without intervention, dissolved and particulate organic waste can degrade water quality, reduce clarity, and deplete oxygen levels. Regular application of ARTECIFE PNSB minimizes maintenance efforts and expenses related to water changes, gravel vacuuming, and the replacement of chemical filter media. This is particularly beneficial in the planted refugium, where it can immediately absorb water-yellowing algal exudates.

Moreover, these naturally occurring, beneficial microbes play a critical role in maintaining a balanced nitrogen cycle. They efficiently capture excess ammonia, nitrite, and nitrate, and can perform nitrogen fixation in environments depleted of inorganic nitrogen sources. This aspect is crucial, as research indicates PNSB (especially Rhodopseudomonas palustris) form symbiotic relationships with stony corals, providing both the coral and its zooxanthellae with a steady supply of nutrients. Both stony and soft corals have been observed directly consuming PNSB, which are rich in protein, vitamins, and carotenoids that enhance color. Additionally, their probiotic effects can significantly lower disease rates across various aquarium inhabitants.

ARTECIFE PNSB is suitable for both freshwater and saltwater aquariums and is completely safe, non-toxic, and non-pathogenic. The color of PNSB may range from yellow to red to purple, depending on pigment content influenced by environmental and dietary factors; thus, product color may vary from yellow-orange to orange-red. The presence of reddish-purple to dark brown bioflocculants, which may form in the bottle, does not compromise product quality. For optimal results, use in conjunction with the companion product PNS YelloSno™ as part of the cost-effective PNS Product Combo. Looking for
