BOYU Gravel Siphon Cleaner 612mm

BOYU Gravel Siphon Cleaner 612mm

BOYU Gravel Siphon Cleaner 612mm is an aquarium gravel vacuum that cleans fish tank substrate by siphoning out dirt and water at the same time. Sold as model GC-303, it is built for South African fishkeepers who want quicker, tidier water changes and a cleaner gravel bed without starting the siphon by mouth.

BOYU positions the GC-303 as a top-of-the-range vacuum cleaner for convenient tank maintenance. It draws debris from in and around the gravel and drains aquarium water efficiently, so routine cleaning and partial water changes can be done in one session. It is a popular choice because one tool covers several jobs: removing solid waste, stirring up the gravel so trapped dirt is released, and emptying old water to keep your aquatic environment clean and healthy.

Key Benefits

• Thorough, fast substrate cleaning: siphons dirt from within and around the gravel to help keep your aquascape in good condition.
• Efficient water removal: drains aquarium water at the same time, which makes it practical for partial water changes.
• Shake-to-start siphon: you start the flow by shaking the tube, so there is no need to suck on the hose end and risk swallowing aquarium water.
• Triangular prism-shaped intake tube: the angled profile reaches into corners, along the glass and between décor where waste tends to collect.
• Integrated fish and gravel guard: a built-in strainer helps stop fish and substrate from being drawn up the tube while dirt is removed.
• On/off flow switch: lets you control the water flow, so the cleaner can be used in a fish tank of any size.
• Multi-function design: combines waste removal, gravel agitation and water draining in a single tool.

How to Use

• Have a bucket ready beside the aquarium.
• Submerge the intake end of the tube in the fish tank.
• Place the other end of the hose in the bucket, making sure the outlet sits lower than the aquarium's water level so the siphon can flow.
• Shake the tube to start the siphon. No mouth suction is needed.
• Push the intake tube into the gravel and move it slowly over the substrate. The swirling action lifts dirt and solid waste, which is carried out with the water.
• Use the on/off switch to control or stop the flow as you work around the tank, or once you have removed enough water.
• Refill the aquarium with treated, temperature-matched water to suit your local tap supply.

Suitable For

• Freshwater fish tanks with gravel substrate that need regular cleaning.
• Hobbyists who want to combine gravel vacuuming with partial water changes.
• Planted and decorated aquascapes where the angled tube helps reach awkward corners.
• Anyone who would rather not start a siphon by mouth.

Compatibility

Because the water flow is controlled by an on/off switch, the cleaner can be used in a fish tank of any size. Think about your tank's depth and substrate cleaning needs when choosing a siphon cleaner. The 612 mm intake tube suits a wide range of standard home aquarium setups.

Frequently Asked Questions

Do I need to suck on the hose to start the BOYU siphon?
No. You start the siphon by shaking the tube, so there is no mouth suction and no risk of swallowing tank water.

Will the gravel cleaner suck up my fish or gravel?
It has an integrated fish and gravel guard/strainer that helps keep fish and substrate out of the tube while dirt and waste are siphoned away.

How long are the tubes?
The intake tube is 612 mm (24.1") and the water tube is 1700 mm (66.9"). The supplier describes the unit as a two-metre siphon cleaner.

Can I use it on a small tank?
Yes. The on/off switch controls the water flow, so you can use it in a fish tank of any size and avoid draining too much water from smaller setups.

Why won't my siphon flow?
Check that the outlet end in the bucket sits lower than the aquarium's water level. The siphon needs this height difference to flow.

Can I do a water change at the same time as cleaning the gravel?
Yes. The GC-303 removes dirt from the substrate and drains aquarium water in the same session, which makes routine partial water changes quicker.
