A diaphragm or piston pump that pushes air through tubing to airstones, sponge filters, or venturi devices - the simplest source of gas exchange in aquariums.
Price: Budget
For: Both $10-$150
📖 Overview
The humble air pump powers most quarantine tanks, fry tanks, and sponge filters in the hobby. By driving air through an airstone or sponge filter, it creates surface agitation and dissolved oxygen replenishment. Modern silent-piston pumps (Tetra Whisper, EHEIM) run for years without noticeable noise; commercial linear-piston pumps drive entire fish rooms.
🎯 Purpose
Oxygenation, driving sponge filters, powering air-driven ornaments, protein skimmer air injection.
