Product Description

The small air pump is designed for aquariums up to 20 Gallons, with a dimension of 4×2.75×1.5 inches. It is quiet and steady, with 4 rubber feet that keep it from sliding around to reduce noise further. This air pump is great for running a small air stone, sponge filter, air bubbler decoration, or other bubble ornaments for a small fish/shrimp tank or hydroponic system.

Features

• The small aquarium air pump puts out a nice consistent flow of bubbles for fish to swim through and keeps the water oxygenated.
• This nano fish air pump works with a small sponge filter, air disc, or a small bubbler decoration.
• The mini fish tank air pump creates a steady stream of air for small betta tanks, brine shrimp hatcheries, and small hydroponic setups.
• 4 rubber feet at the bottom keep it from sliding around to reduce noise further.
