NP Reducing BioPellets are a carbon-source media for reef aquarium owners who want to lower nitrates and phosphates without daily dosing. The pellets are placed in a filter chamber, where bacteria colonise and multiply on them. The 1000 ml pack is sized according to the total volume of the system.
Why it matters
- Organic carbon base: the pellets are made of biodegradable polymers, which bacteria use as their carbon source to remove nitrates and phosphates.
- Localised bacterial growth: bacterial activity is concentrated in the filter chamber rather than spread through the whole tank.
- Competition with nuisance microbes: the bacteria growing on the pellets compete with undesirable microorganisms, including cyanobacteria.
- Low maintenance: the media is not replaced; it is topped up periodically, roughly every 3–6 months, as the pellets shrink.

What it works with
The media is intended for reef aquariums with corals and other invertebrates, where excess bacterial biomass is taken up by inhabitants and removed by a protein skimmer. It works in canister filters or fluidised bed reactors, with the fluidised bed giving better results and reducing detritus buildup. Use of ozone or UV upstream of the pellets slows bacterial colonisation, so the filter needs more time to mature.

Frequently asked questions
The pellets are made from biodegradable polymers that serve as an organic carbon source. Bacteria settle and multiply on them and consume nitrates and phosphates, and the excess bacteria are taken up by corals and other tank inhabitants or removed by the skimmer.
On average, it takes about 2 to 4 weeks for enough bacteria to develop and for nitrate and phosphate reduction to begin.
As bacteria consume them, the pellets gradually shrink, so you add about 100 ml every 3 to 6 months. They are not replaced entirely; new pellets are only added to make up for the loss.
The recommended dose is 0.5 to 1 litre for every 500 litres of system volume. If nitrate or phosphate levels are already high, start with a smaller amount and increase it gradually to avoid a sudden drop in parameters.
A strong skimmer and good water aeration are required, along with high water flow through the pellet media to prevent hydrogen sulfide gas. A fluidized reactor gives better results than a canister filter because it prevents detritus buildup, and ozone and UV passing through the pellets slow bacterial colonization.
