Aquarium Air Stone Disc Bubble Diffuser - 10 cm, Grey and Black

This 10 cm air stone disc for aquariums and hydroponic systems has a dark grey stone disc in a black rim, with a connector that fits air tubing with a 4 mm inner diameter. It turns the air from your pump into a curtain of fine bubbles that adds oxygen and moves the water.

Features

• Finely compressed mineral material releases small bubbles to aerate the water and add movement in fish tanks and hydroponic setups.
• The 10 cm disc connects to 4 mm inner diameter air tubing, so it slots straight onto a hose line of that size.
• Easy to use: connect it to the air hose and pump, and clean the surface regularly for longer, more efficient use.
• Soak the stone in water for about 15 minutes before first use, and replace it every few months once it clogs with dust, bacteria and algae.
