Pawfly Aquarium 8 Inch Air Stone Cylinder for Larger Pump Bubble Diffuser for Outdoor Pond Garden Circulation System and Large Fish Tank, 2 Pack

Features

• Steadier Bubbles: Use superior rubber material which allows abundant dense and even bubbles to spout from the cylinder. An ideal way to fully aerate your water tanks.
• Larger Size: Measure 2" D x 8" L. Fit for reservoirs like hydroponic systems, ponds, gardens and some large aquariums or tanks. NOT for small fish tanks.
• Model: ASE-504; Jetting volume: 24 L / min; Recommended air pump power: > 7 W. Stainless steel air inlet fits standard 3/16" ID tubing. Well-built to be used 24/7.
• Stable in Water: Weigh 0.75 lb and come with 2 square holders at both ends to increase stability. It always lies steadily in the tank without moving easily when bubbling.
• Easy to Use: Soak it completely in water for more than 3 hours before use. Simply clean the stone by wiping the dirt off its surface instead of brushing it after use.
