ClarEx 1500 External Canister Filter

ClarEx 1500 External Filter

ClarEx 1500 is the most powerful model in the series, designed for freshwater and marine aquariums with a capacity of 400–600 liters.

It provides intense circulation and efficient multi-stage filtration even in large tanks with high biological loads.

The design is based on a proven multi-layer filtration system that effectively removes mechanical impurities and

supports stable biological balance in the aquarium. The device combines high performance with quiet and energy-efficient operation.

Maximum Filtration Efficiency

The filter is equipped with a modular filtration basket system, allowing flexible adjustment of media configuration to the specific needs of the tank.

The standard set includes filtration media:

• mechanical

• biological

This means the device is ready to operate immediately after installation, without the need to purchase additional cartridges.

Strong circulation supports even distribution of nutrients and oxygen throughout the aquarium,

which is particularly important in planted tanks and those with a high fish population.

Precise Control and Reliability

ClarEx 1500 has been designed for full control and hassle-free operation:

• smooth flow adjustment using levers at the valves

• integrated air pump system facilitating filling

• stable, solid construction

• quiet operation even at high performance

These solutions ensure quick startup and minimize the risk of airlock in the system.

Heater Ready & CO₂ Ready

The heater ready design allows for the safe placement of the aquarium heater inside the filter housing, which:

• reduces the amount of equipment in the tank

• improves the aesthetics of the arrangement

• increases the efficiency of heat distribution

• The dedicated CO₂ ready port allows for direct connection of the CO₂ system, making the filter a suitable solution for large high-tech planted aquariums.
