hygger Aquarium Air Stone Bubbler Kit, Clear 45 mm Double-Ring Oxygen Diffuser

The hygger aquarium air stone is a compact bubbler kit for adding aeration to aquariums, hydroponic systems, and small ponds, with a transparent acrylic body and double aeration ring.

• EVA bubble-making material — designed to resist corrosion and clogging compared with traditional ceramic air stones.
• Transparent acrylic body — blends into an aquarium and stays in place while operating.
• Double aeration ring — creates dense bubbles quietly to help oxygenate the water.
• Complete kit — includes an air tube, suction cup, and stainless steel pliers.
• Works with a 2W or larger air pump — fits freshwater, seawater, and reef aquariums, as well as hydroponics and small ponds.

For fish tanks and other water setups that need added aeration, this diffuser produces a steady stream of bubbles without the visible bulk of an opaque stone. Its clear body is easy to conceal underwater, making it useful when you want aeration while keeping the diffuser less prominent.

How does the hygger air stone aerate water?

The hygger air stone uses two aeration rings to release dense bubbles quietly. The bubbles add oxygen to the water; the diffuser is also designed to lower CO2 and raise pH. Its EVA bubble-making material is more corrosion-resistant than traditional ceramic air stone material and is designed not to clog during use.

• Air stone diameter: 1.77 in (45 mm); height: 0.6 in (1.52 cm).
• Weight: 2 oz (57 g) per air stone.
• The transparent acrylic body is easy to hide underwater and does not move while operating.

What setups is this bubbler compatible with?

Use the hygger air stone in freshwater or seawater and reef aquariums, fish tanks, hydroponic systems, or small ponds. It is driven by an air pump rated at 2W or more, so match your pump to that minimum requirement before setting it up.

• Included air tube length: 2 m.
• A suction cup is included to help position the diffuser.
• If the bubbles are large, use the included pliers to tighten the air stone as much as possible.

How do I set up and clean the hygger air stone?

Connect the hygger air stone to the air pump and place it in water; soaking it before use is not necessary. For algae buildup, take the air stone apart and gently wipe it with a soft cloth.

• The kit includes one air stone, one air tube, one suction cup, and stainless steel pliers.
• Cleaning algae does not require disinfectant or brushes.

This kit suits aquarium keepers and hydroponic growers who want a discreet diffuser and already have an air pump rated at 2W or higher. Its clear acrylic body, included tubing and positioning accessories, and compatibility with several water setups make it a practical choice for adding aeration to those environments.
