Biopellets NP Dupla Marin

Filter medium for Phosphate and Nitrate reduction.

Filter medium for nitrate and phosphate reduction

DuplaMarin Biopellets NP is an easy to use filter material for reducing the nitrate and

phosphate content in the marine water aquarium. The Biopellets NP consist to100 %

of biologically degradable polymers with the additional benefit of providing a surface

area and nutrient source for nitrate-removing bacteria. As they grow, the bacteria use

the Biopellets NP as a source of carbon (energy source) and the phosphate and nitrate

in the aquarium water as a source of nitrogen and phosphor. The waste products

nitrate and phosphate are converted into microbial biomass and then removed from

the aquarium by skimming or as an additional food source (bacterial plankton) by

filter feeders, mussels, sponges and corals. Even after a start-up phase of 2–4 weeks

sufficient bacteria have formed to reduce phosphate and nitrate levels. Filtering via

Biopellets NP is a probiotic method where an organic carbon source is provided so

that heterotrophic marine bacteria promote nitrification and denitrification due to the

growth of biomass.

Application: DuplaMarin Biopellets NP have been developed for application in a

pellet or fluidised bed reactor for marine water aquaria. Abrasion causes the biomass

produced on the Biopellets to come loose and is then skimmed by the protein skimmer.

Part of the detached biomass is available to filter feeders and corals as a supplementary

source of food. Vigorous skimming of the aquarium water is therefore necessary for

extracting nutrients and gaseous exchange. Depending on the circulation in a pellet

or fluidised bed reactor, more phosphates or more nitrates can be reduced. A fast

running fluidised bed reactor or pellet reactor reduces more phosphate, a reactor that

runs more slowly reduces more nitrates. Regulating the flow rate therefore allows you

to adapt a pellet of fluidised bed reactor perfectly to the respective water conditions in

the aquarium.

A standstill of the Biopellets NP or an inadequate flow rate in the reactor can result in

the material clumping together as well as the formation of hydrogen sulphide. This can

be identified by an unpleasant smell of rotten eggs. The outlet of the pellet or fluidised

bed reactor should be located in the immediate vicinity in front of the inlet or the

suction pump of the protein skimmer for an efficient removal of the detached biomass

from the system.

Initially, 50 ml Biopellets NP should be used for every 100 litres of aquarium water.

This quantity can be gradually increased if necessary. A maximum of 200 ml Biopellets

NP should be used for every 100 litres of aquarium water. To a avoid limitations of

phosphates and nitrogens, other adsorbers, such as phosphate adsorbers, should not

be used. Biopellets NP are used up by bacteria and should be renewed very 6 months.
