NP-Active Pearls are a pure, specially made biodegradable carbon (polyhydroxyalkanoates commonly referred to as PHA) for use in aquaria. PHAs are made from bacteria so they are truly 100% natural and completely biodegradable into carbon dioxide and water.
In the aquarium environment, bacteria use NP-Active Pearls to assimilate phosphate and nitrate in the water to grow, producing bacterial biomass which is then easily harvested.
NP-Active Pearls are made specifically for use in aquariums and are the result of a unique partnership between Telles, Aquaculture Systems Technology and DrTims Aquatics.
NP-Active Pearls are PHA based and 100% pure. Other bio-pellets are made from such polymers as hydroxybutyric acid (PHB), polylactic acid (PLA) and polybutyleneadipate-co-butyleneterepthalate (PBAT). In addition, other bio-pellets may not be as pure as NP-Active Pearls. The main use of all biodegradable polymers is to make biodegradable products such as forks, knifes, plates, etc. In order to do this, however, the polymer must be combined with binders, fillers and other materials.
NP-Active Pearls are free of all these impurities to make them suitable for worry-free aquarium use. Other bio-pellet companies do not disclose the source or purity of their pellets.
NP-Active Pearls need to be placed in a reactor of some type that keeps the pearls moving and brings oxygenated water to the Pearls. They should NOT be mixed with activated carbon or GFO, nor should they be placed in a bag and laid in a sump.
