Tetra APS Air Pumps

It's been running nonstop for two weeks next to my couch and I genuinely have to check the bubbles to know it's on, the sound-absorbing chambers make that much difference. The rubber feet keep it from sliding around too, so it's stable and quiet even on a glass shelf.

Swapped out my old noisy pump for this one and the difference is night and day — the rubber feet really do kill the vibration against my cabinet. My tank sits in the bedroom now and I can actually sleep through the night.

Honestly forgot this thing was even running until I checked the tank last night — the rubber feet and sound chambers really do kill the hum. My old pump rattled the whole shelf, this one I can barely hear from the couch.
