NP BioPearls
For Nitrate and Phosphate Reduction

NP BioPearls are pelletized biodegradable polymers that make waste from the water, mainly
nitrate and phosphate, are converted into bacteria. This keeps the aquarium water achieve
natural marine water level.

The new formula NP Reducing BioPearls are composed of 100% pure biologically degradable
 polymers that can be placed in a fluidized filter or mini filter canister. The pellets will allow
aerobic growth of bacteria which consequently will consume nitrate and phosphate simultaneously.
The bacteria will use up the carbon from the BioPearls, whilst nitrogen and phosphorus are
taken from the water as nitrate and (ortho)phosphate. This conversion of organic BioPearls
(together with inorganic nitrogen and phosphorus) into microbial biomass is called immobilization.
In addition, anaerobic layers will develop, resulting in additional denitrification.

To avoid the sensitive marine animals being unadapted for sharply reducing of NO3 and PO4,
 we recommend adding NP BioPellets in a successive way. For example: BioPearls should
 added in 200L aquarium water as follows:

Caution：
-Maintain sufficient water flow through the NP BioPearls, to prevent production of hydrogen
 sulfide gas.
-The use of NP BioPearls in marine aquariums must be accompanied by the use of a protein
  skimmer to achieve the export of bacteria and assimilated nutrients. It is not necessary for the
  outlet of the filter containing pellets to be positioned near the intake of a protein skimmer,
  but it is necessary to have a protein skimmer running on the system.  
-The use of ozone and UV will negatively affect bacterial recruitment of the BioPearls and increase
 the maturation time of the filter. So we won’t reocommend use the NP BioPearls with ozone
 and UV at the same time when cultivating bacteria.
