The 4-inch air stone cylinders feature durability, steady bubbles, and a high dissolved oxygen rate, making them optimal for aerating your water reservoirs and livening up your aquatics. Made from enduring and washable silicon carbide, they are well-built to keep stable in water and produce constant bubbles for fish's breath, perfect for aeration in fish tanks, ponds, DWC reservoirs, aquariums, and more.

Bigger air stones need more powerful pumps to produce more bubbles, while small pumps go well with small air stones. The cylindrical shapes can exist in many sizes and colors, with disc shapes staying steady at the bottom of the tank and globular ones producing more bubbles in the case of the same size.

The large cylindrical bubblers are well-built for continuous use, requiring an air pump more than 7 W to run the stones for constant bubbles. With a large jetting volume of 5 L/min, each bubbler produces enormous medium bubbles and always keeps still due to its stable construction. Users need to soak the stone in water for about 1 hour before use and clean it regularly as it gets clogged, replacing it when not working properly.
