## Long description

ZOLUX advanced 21 cm aquarium gravel cleaner (model 376624) is a manual substrate siphon designed for routine removal of debris and waste from gravel and sand in small to medium aquariums. The 21 cm working length makes the tool compact and easy to handle while allowing targeted cleaning of the substrate during water changes. It operates by creating a siphon action that draws out suspended particles and detritus without requiring electrical power, helping to maintain water clarity and overall tank hygiene.
Advantages
The ZOLUX advanced gravel cleaner provides precise control over substrate cleaning thanks to its short working length and ergonomic design, which suits frequent maintenance tasks. Its manual siphon principle is simple to use and reduces disturbance to plants and fish compared with more aggressive mechanical devices. The compact size and straightforward operation also make it convenient to store and transport, and it can be used during partial water changes to remove settled waste and uneaten food.
Suitable for
Small to medium freshwater aquariums
Routine partial water changes and substrate maintenance
Removing settled detritus from gravel or fine sand
Hobbyists who prefer a manual, non-electrical cleaning method
Key specifications
Working length: 21 cm, suited for compact tanks and targeted cleaning
Operation: manual siphon action for debris and waste removal
Compatible substrates: gravel and fine sand
Use case: designed for routine maintenance and partial water changes
How to use
Place the gravel cleaner inlet on the substrate surface and start the siphon according to the included instructions or by manual priming. Move the inlet gently across the gravel or sand so that settled particles are lifted and carried away by the flow while avoiding excessive disturbance of plants and fauna. Perform substrate cleaning during partial water changes to remove accumulated detritus; stop siphoning before removing too much water and adjust the depth and speed of movement to control how much substrate is disturbed.
Usage recommendations
Use the cleaner during regular partial water changes to maintain water clarity and reduce organic buildup. Rinse the device after each use and store it dry in a cool place. For planted tanks, work slowly around roots and delicate plants to avoid uprooting. Inspect hoses and connections periodically for wear and replace parts if leaks or reduced siphon efficiency occur.
