Gravel Cleaner Edge triangular 14×7 cm with 12/16 mm hose 2 m – sera

The Gravel Cleaner Edge triangular 14×7 cm with 12/16 mm hose 2 m by sera is a compact gravel vacuum designed for targeted substrate maintenance in small to medium aquariums. Its triangular cleaning head reaches into corners and along walls to remove uneaten food, detritus and organic waste from gravel and sand without displacing large amounts of substrate. The included 2 m flexible hose with a 12/16 mm diameter supports siphon-assisted water flow for convenient debris extraction and clearer water.

Advantages

The triangular shape allows precise cleaning along tank edges and in tight spaces where round heads cannot reach. The 14×7 cm head balances cleaning coverage with minimal disturbance to decor and plants. A 2 m flexible hose provides mobility around the aquarium and can be used for direct siphoning or connected to compatible filtration or waste collection setups. The design reduces cloudiness and organic buildup while preserving most of the substrate.

Suitable for

• Small to medium freshwater and planted aquariums
• Targeted removal of food waste and organic detritus from gravel and sand
• Cleaning along tank corners, walls and under decorations
• Routine maintenance to maintain water clarity and reduce nitrate accumulation

Key specifications

• Cleaning head shape: triangular
• Cleaning head dimensions: 14 × 7 cm
• Hose length: 2 m
• Hose inner/outer diameter compatibility: 12/16 mm
• Suitable substrates: gravel and sand

How to use

Insert the triangular head gently into the substrate near the area to be cleaned and move it slowly along the gravel, allowing siphon action to lift debris into the hose. For initial use, start a siphon according to standard aquarium siphoning technique or connect to an appropriate suction source compatible with 12/16 mm tubing. Avoid vigorous stirring to prevent excessive substrate loss; perform short passes until visible debris is removed. Monitor water level and stop siphoning before losing too much water, then top up with dechlorinated water at matching temperature.

Usage recommendations

Use regular, moderate cleaning intervals to prevent excessive organic buildup while preserving beneficial bacteria in the substrate. For planted aquariums, work carefully around roots and perform partial water changes after cleaning to maintain stable parameters.
