## Summary description

Hagen MARINA ODMULACZ MEDIUM is a manual aquarium gravel cleaner designed for routine substrate maintenance in small to medium tanks. The device functions as a siphon-based cleaner to remove debris and waste from gravel and sand without full water change. It is suitable for spot cleaning between water changes, aquarium upkeep, and reducing detritus buildup to support fish health.

## Long description

Hagen MARINA ODMULACZ MEDIUM is a manual substrate siphon designed for routine gravel and sand maintenance in small to medium aquariums. The device uses a simple siphon principle to extract debris and organic waste from the substrate surface and interstices without requiring a full water change. Its form factor and flow control make it suitable for targeted cleaning of planted and unplanted tanks where gentle yet effective removal of detritus is needed to help maintain water clarity and reduce pollutant buildup.
Advantages
The Marina medium gravel cleaner provides controlled suction that removes waste from gravel and sand while minimising disturbance to beneficial bacteria and plant roots. Its manual operation requires no electricity and allows precise spot cleaning. The design includes a rigid intake tube and flexible hose to reach across the aquarium with minimal splashing, and it efficiently separates heavier particles from suspension so that removed material concentrates in the outflow rather than returning to the tank.
Suitable for
Routine substrate maintenance in small to medium aquariums
Spot cleaning between full water changes
Removal of uneaten food, fish waste and plant debris from gravel or sand
Maintaining water clarity and reducing detritus buildup
Key specifications
Operation: manual siphon action for controlled suction
Designed tank size: small to medium aquariums
Applicable substrates: gravel and sand
Main components: rigid intake tube, flexible discharge hose, siphon mechanism
Typical use: spot cleaning without full water change
How to use
Position the intake tube over the area of substrate to be cleaned and start the siphon according to the manufacturer's priming method (manual squeeze, bulb or initial fill). Move the intake slowly across the gravel or into the sand so that debris is lifted and sucked into the tube while larger substrate particles fall back. Direct the outflow to a bucket or drain and monitor water level while cleaning to avoid removing excessive water. After use, flush the hose and tube with clean water and allow to dry before storage.
Usage recommendations
Use the Marina medium gravel cleaner for short, regular cleaning sessions rather than deep excavation. For planted aquariums, work gently around roots and avoid prolonged suction in one spot to preserve plant stability and beneficial microfauna.
