## Summary description

External aquarium filter Tetra EX 500 Plus (T302808) designed for aquariums with volume below 100 litres. It provides mechanical, biological and chemical filtration via multi-stage filter media, includes an integrated pump and adjustable flow, and is intended for freshwater setups to maintain water clarity and healthy conditions for fish and plants.

## Long description

The Tetra EX 500 Plus external aquarium filter (model T302808) is designed for freshwater aquariums up to 100 litres. The unit integrates a pump and a multi-stage filter cartridge system that delivers mechanical, biological and chemical filtration to reduce cloudiness, remove suspended particles and support beneficial bacterial colonies. An adjustable flow control allows tailoring circulation to the needs of fish and plants while the compact housing mounts externally to maximise internal aquarium space.
Advantages
The filter combines mechanical pre-filtration with biological media and activated carbon to address a range of water quality issues without requiring complex setup. The integrated adjustable pump simplifies installation and makes it possible to regulate water movement for delicate species or planted tanks. The external design keeps filtration media and maintenance access out of the display area, and replaceable media cartridges allow straightforward servicing.

How to use
Install the external filter according to the manufacturer's instructions, positioning the unit beside or below the aquarium and connecting inlet and outlet hoses securely. Prime the pump if required, set the flow rate with the integrated control to match the aquarium inhabitants and start the unit. Regularly inspect and replace mechanical pads and chemical media according to usage and water parameters; maintain biological media gently to preserve beneficial bacteria. Follow safety precautions when handling electrical equipment near water.
Usage recommendations
For best results, match the flow rate to the aquarium’s stocking level and plant requirements, perform regular partial water changes and rinse mechanical media in aquarium water during maintenance to avoid disturbing biological filtration.
