Key specifications

• Type: Manual siphon gravel cleaner
• Intended use: Gravel and sand substrate cleaning
• Operation: Hand-initiated siphon flow, no power required
• Design: Compact, lightweight and easy to handle

How to use

Submerge the intake tube into the aquarium substrate and initiate siphon action according to the manufacturer's method (squeeze, shake or mouth suction as appropriate and safe). Move the intake gently over the gravel surface to lift waste into the flow while allowing heavier substrate particles to fall back. Direct the outlet into a bucket to collect removed water and debris. Monitor water level and stop siphoning when the desired volume has been removed or when the substrate appears clean. Rinse the unit thoroughly after use and allow to dry before storage.

Usage recommendations

Use the Marina small gravel cleaner during regular partial water changes to maintain water quality and reduce detritus buildup. Avoid prolonged agitation of sticky or very fine substrates and perform gentle passes to prevent excessive disturbance of plants and livestock. Rinse the device in dechlorinated water when used in planted aquaria to protect sensitive roots and beneficial bacteria.
