What does the PNS Product Combo do?
What's in the Combo?
PNS Probio™ contains cultures of live PNSB. These naturally occurring and highly beneficial microbes contribute to a balanced nitrogen cycle, efficiently taking up excess ammonia, nitrite and nitrate. On the other hand, where sources of inorganic nitrogen have been depleted (ultra-low nutrient systems), they are capable of performing nitrogen fixation. This is extremely important, as recent research has revealed that PNSB (e.g. Rhodopseudomonas palustris) form critical mutualistic associations with stony corals, providing both the coral and its zooxanthellae with a "built-in" source of nutrients. Also, stony and soft corals alike have been shown to directly consume PNSB, which are rich in protein, vitamins and carotenoids. Plus, they act as powerful probiotics! Regular use of PNS Probio™ cleans the aquarium by consuming excess organic matter and nutrients and so reduces the amount of time/money spent on water changes, gravel vacuuming, changing chemical filter media, etc. Composed of all-natural chitin fragments that are coated with R. palustris, PNS YelloSno™ effectively simulates a marine snowfall. After a proprietary curing process, this nutritous coral food is preserved for a long shelf life by flash pasteurization. With a wide particle size range, it may be captured and consumed by a large variety of suspension-feeding animals (e.g. corals). It is rich in protein, vitamins and amino acids. Why use the combo? While each of these products works great on its own, the pair works even better in tandem. This is because you gain the water-cleaning/probiotic qualities of the live product (PNS Probio™); proliferation of the live bacteria is promoted by use of the food (PNS YelloSno™) which provides a rich source of B vitamins (which R. palustris cannot synthesize but requires for growth).

Directions and Usage for PNS Probio™:
Shake the bottle to gently but thoroughly mix contents. Pour directly into the aquarium in an area of high flow. Turn off UV sterilizers for 24 hours. When used to establish new aquaria, this product is best added just after the system is "cycled" and just prior to stocking livestock. However, it may be used at any time to improve coral health/growth or to remove sludge, nutrients or dissolved organic matter. Store at room temperature. Dosage: Add up to 16.9 fluid ounces PNS Probio™ per 400 US gallons (approximately 1.25 ml/gal). Risk of overdose is extremely low with these safe, probiotic bacteria.Directions and Usage for PNS YelloSno™:
Shake the bottle thoroughly for fine particle sizes or lightly for larger particle sizes. Pour small amount of dose (approximately 10%) directly into the main tank in an area of high flow to prime animals for feeding (preferably just after lights-out). Once corals and other suspension feeders have exhibited a feeding response, add the remaining portion. While certain strong, natural odors may become evident, they are normal and dissipate shortly after use. Keep refrigerated at all times! Dosage: Add up to 16.9 fluid ounces PNS YelloSno™ per 500 US gallons per feeding session (approximately 1 ml/gal). As with all foods, it is best used sparingly to maintain good water quality.

For many lifelong aquarists, that feeling of captivating awe never goes away. Thankfully, the intimidating task of learning how to actually build and maintain a saltwater aquarium system does go away. In fact, …

Copepods (pods) are essentially required for any reef aquarium. They perform three important ecological tasks: (1) Graze on benthic microalgae, (2) scavenge detritus, and (3) serve as food for diverse zooplanktivores. They are so ubiquitous in nature, and even in captivity, that they commonly invade new tanks as hitchhikers on live rock, corals, etc. While …

In the Age of the Reef Tank, many cool (but not reef-safe) saltwater fish families that were once extremely population are now relative rarities. One such group, for sure, is the filefishes. This is too bad, as filefish are intelligent and possess abundant character. They are also quite “marine” in appearance and behavior; even the …
