AQPET BIONEPTUNE NEXUS PREFILTER

The Bio Neptune NEXUS by AQPET is an innovative external pre-filter , designed with the aim of optimizing the performance of your aquarium's filtration system. Thanks to a technical, modular and functional design, this device represents a strategic extension of the filtration system , playing a fundamental role in protecting, enhancing and simplifying the management of the aquarium.

Suitable for both freshwater and marine aquariums , the NEXUS acts as a highly effective primary barrier , intercepting debris, sediment and organic residues before they reach the primary biological or mechanical filter. The result is a more efficient system, less subject to wear, with reduced maintenance times and significantly higher water quality.

Preventive mechanical filtration – the first defense against water quality degradation

Positioned on the suction or delivery line, the Bio Neptune NEXUS performs first-level mechanical filtration , selectively blocking:

• suspended particles in the initial phase (sand, plant residues, solid debris);

• decomposing organic residues (food scraps, feces, biofilm);

• turbidity caused by temporary disturbances of the substrate.

By intercepting these materials before they reach the main filter , the Nexus significantly reduces:

• the risk of clogging of sponges or biological materials ;

• the decrease in the flow rate of water ;

• the accumulation of organic substances responsible for the formation of ammonia and nitrites.

This allows for a better balancing of the ecosystem , with visually clearer water, fewer pollutants to manage and greater stability of the chemical-physical parameters.

Expandable module for filter materials – an upgradeable and customizable system

In addition to the pre-filtering function, the Bio Neptune NEXUS stands out for the presence of an internal space designed for the insertion of additional filter materials . This compartment can be used for:

• integrate sponges with differentiated porosity for further mechanical refinement;

• insert activated carbon, zeolite or specific resins for a targeted chemical action (removal of chlorine, heavy metals, tannins, phosphates);

• enhance biological filtration by adding ceramic materials with a high specific surface area.

Thanks to this versatility, the Nexus transforms into a multifunctional module , suitable for supporting high population density systems, particularly delicate aquariums (such as marine or coral aquariums), or highly planted layouts.

Simplified maintenance with integrated valves – quick access without interrupting flow

One of the distinctive elements of the Bio Neptune NEXUS is the integrated isolation valve system, which allows for quick and safe dismantling of the pre-filter even when the system is active.

Thanks to these valves:

• it is possible to interrupt the incoming and outgoing flow , isolating the Nexus from the hydraulic circuit without having to disconnect the entire system;

• water leaks are avoided during maintenance operations;

• internal access is easy to remove or replace filter materials, without contaminating the main filter.

This makes the Nexus a highly practical accessory, ideal for aquarists who want to simplify their routine maintenance , reducing time and risks.

Universal installation – compatibility with most external systems

The Bio Neptune NEXUS is designed to be easily installed on any external filter system , thanks to its standard connections compatible with the main pipe diameters used in aquariums. It can be positioned:

• on the suction line to block debris before it reaches the filter;

• on the delivery line to further refine the filtration or for the controlled release of additives.

The compact body and cylindrical design make it easy to fit into the technical compartments of filter cabinets, without taking up excessive space or requiring invasive modifications.
