NP Biopellets Filter Media 1000ml Information

Product Manuals & Documentation

Treat waste products in your aquarium using a filter media that is very nature friendly. The NP Biopellets Filter Media from Pet Store will make the quality of your aquarium's water better than before. The principle of immobilization is the basis of its cleaning performance and method of filtering. The biopellets convert phosphates and nitrates into beneficial bacteria. This activity will in turn make the water cleaner and safer for your pets.

These biopellets were made of polymers that are biologically degradable. Further, the manufacturers made sure that the biopellets can be contained in a filter canister or a fluidized filter. Hence, the said pellets can allow aerobic growth of those nitrates and phosphates that were converted into bacteria. Further, the phosphorus and nitrogen that supplements the growth of the bacteria outputs come from the water, while they take the carbon from the biopellets. Even better, there will be anaerobic layers that will develop during the process of immobilization. They will later on result as additional aids in denitrifying the water in your aquarium. Aside from that, surplus which the bacteria produce will be consumed by sponges, and corals, or by the filter itself.

With this package of1000ml of biopellets, unwanted particulates in your aquarium will all be "immobilized".

How it works
The positive effects of NP-reducing BioPellets on water quality are based on the principle of immobilization. Waste products from the water, mainly nitrate and phosphate, are converted into bacteria. This keeps the aquarium water clean.

NP-reducing BioPellets are composed of biologically degradable polymers that can be placed in a fluidized filter or 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 BioPellets, whilst nitrogen and phosphorus are taken from the water as nitrate and (ortho)phosphate. This conversion of organic BioPellets (together with inorganic nitrogen and phosphorus) into microbial biomass is called immobilization. In addition, anaerobic layers will develop, resulting in additional denitrification.

The surplus of bacteria will be consumed by filter and suspension feeding organisms such as sponges and corals, or skimmed off by a protein skimmer. On average this solid wodka method takes 2-4 weeks to give rise to sufficient bacteria to allow nitrate and phosphate levels to drop. The main advantage of this method over using Wodka or sugar as a carbon source is that NP-reducing BioPellets stimulate local growth of bacteria in a filter compartment, instead of all over in the aquarium where they may clog up pipes and hoses. They also prevent the growth of cyanobacteria, as the bacteria growing on NP-reducing BioPellets will compete with these phototrophic nuisance microbes. Finally, NP-reducing BioPellets will save the aquarist a lot of time, as no daily dosages of carbon are required.

Product guidelines
NP-reducing Biopellets can be placed in canister filters or fluidized reactors. The latter configuration may yield better results, and prevents detritus buildup. A proper starting dosage is 0.5-1 liter of pellets per 500 liters of system volume (12,5-25 fl. oz. for every 100 USG). After about 2-4 weeks, nitrate and phosphate levels should start decreasing. For some aquaria experiencing heavy feeding, higher dosages are appropriate. Examples are aquaria which house large quantities of azooxanthellate corals, sponges, tunicates or large schools of Anthias fish. Dosages may be increased indefinitely, provided the aquarium water is sufficiently aerated.

NP-reducing BioPellets are consumed by bacteria, which is why new pellets need to be added every 3-6 months to compensate for digested substrate. This can be seen during inspection of the filter. These figures however depend on aquarium conditions and are strongly influenced by feeding regimes and livestock. Taking regular measurements of both nitrate and phosphate levels in the aquarium is recommended, after which dosages may be increased or decreased.

We also suggest placing the outlet of the pellet filter in front of a protein skimmer, to limit the amount of bacteria entering the system. This has the additional benefit of increased gas exchange (CO2-removal and O2-addition). The pellets should never be used without sufficient aeration, as this may lead to low oxygen and pH levels, especially during night time. Proper aeration can be established with air pumps and protein skimmers.

When heavy feeding is required, it is recommended to combine the pellets with standard phosphate adsorbents. The reason for this is that most aquarium feeds contain higher levels of phosphate than is consumed by bacteria, fish and invertebrates, when compared to nitrogen. Some phosphate adsorbents however deplete alkalinity and may reduce pH. Using phosphate adsorbent media based on iron hydroxide does not have this disadvantage.

Important:
  • Maintain sufficient water flow through the BioPellets, to prevent production of hydrogen sulphide gas.
  • The use of ozone and UV will negatively affect bacterial recruitment of the BioPellets and increase the maturation time of the
