AQPET BIONEPTUNE NEXUS PREFILTER

The Bio Neptune NEXUS by AQPET is an innovative external pre-filter, designed to optimize 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 aquarium management.

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

 

Preventive mechanical filtration – the first defense against water quality degradation

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

 

• initial suspended particles (sand, plant residues, solid debris);
• decomposing organic residues (food scraps, feces, biofilm);
• turbidity caused by temporary substrate disturbances.

   

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

 

• the risk of clogging sponges or biological materials;
• the decrease in water flow rate;
• the accumulation of organic substances responsible for ammonia and nitrite formation.

   

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

 

Expandable module for filter media – an upgradeable and customizable system

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

 

• integrate sponges with differentiated porosity for further mechanical refinement;
• insert activated carbon, zeolite, or specific resins for targeted chemical action (removal of chlorine, heavy metals, tannins, phosphates);
• enhance biological filtration through the addition of ceramic rings or high-surface-area ceramic materials.

   

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

 

Simplified maintenance with integrated valves – quick access without interrupting flow

One of the distinguishing features of the Bio Neptune NEXUS is its system of integrated isolation valves, which allows for quick and safe disassembly of the pre-filter even when the system is active.

 

Thanks to these valves:

• it is possible to stop the inlet and outlet 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 media, without contaminating the main filter.

   

This makes the Nexus a highly practical accessory, ideal for aquarists who want to simplify 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 filtration system, thanks to its standard connections compatible with the main pipe diameters used in aquaristics. It can be positioned:

 

• on the suction line to block debris before it reaches the filter;
• on the return line to further refine filtration or for controlled release of additives.

   

Its 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.
