Explore Neptune Systems at The Tech Den Australia, including A3 Apex controller systems, Trident automated testing equipment, dosing pumps, auto top-off equipment and monitoring accessories. Compare equipment for building, expanding or maintaining an Apex aquarium setup.

Explore the range

• Apex controller systems: A3 Apex, A3 Apex Pro and A3 Apex Jr. Compare each package's included probes, connections and monitoring or control capabilities rather than assuming every system includes the same functions.
• Trident testing and maintenance: Trident equipment for alkalinity, calcium and magnesium testing in marine aquariums, plus reagent kits, calibration solution and a DIY service kit.
• Dosing, top-off and pumps: DŌS Quiet Drive, DDR dual reservoirs, DŌS tubing, the ATK V2 automatic top-off kit, PMUP V2 utility pump and COR-15 return pump.
• Monitoring probes and sensors: Temperature, pH, ORP and conductivity probes, optical and liquid-level sensors, leak detectors and flow sensors in several sizes.
• Modules and connections: Fluid Monitoring Module, probe modules, MXM Mobius Module, AquaBus cables and extension cables.
• Feeding and probe care: Apex-connected AFS automatic feeder, magnetic probe rack and pH or salinity calibration solutions.

Check compatibility before expanding your system

Match each accessory to your Apex generation, required module, available ports and power connections. The AFS feeder requires a compatible Apex controller and is not a standalone feeder. Check the supported equipment for MXM integration and the required connections for pumps, sensors and dosing equipment.

For flow sensors, compare operating flow range, tubing or pipe size, thread type and supplied adapters against your plumbing. Choose calibration fluids for the specific probe or analyser; calibration solutions and Trident reagents serve different purposes.

AquaBus connectors resemble USB connectors but must not be connected to computers or ordinary USB accessories. Follow the manufacturer's installation and maintenance instructions. Trident reagent-kit duration depends on the testing schedule, and the DIY service kit is intended for a working Trident rather than as a general repair solution.
