KSY Aquatics Adjustable Aquarium Bubble Diffuser — Fine Mist Air Stone with Suction Cup, Oxygen Aerator

Not Your Average Air Stone

Standard air stones spit out large, noisy bubbles that rise too fast to dissolve much oxygen. The KSY Aquatics adjustable bubble diffuser breaks air into a dense column of ultra-fine mist — dramatically more oxygen exchange with quieter, smoother operation. Your fish get more oxygen. Your ears get peace and quiet.

Adjustable Output — One Twist Controls It All

Turn the control knob to dial bubble intensity up or down. Crank it for maximum aeration during a heat wave. Dial it back for gentle, decorative bubbling at night. One diffuser does the job of a whole bag of fixed-size air stones.

Strong Suction Cup — Stays Where You Put It

A single large suction cup anchors the diffuser firmly to any glass surface. No floating, no drifting, no readjusting every water change. Press it on, and it stays.

Fine Mist, Not Big Bubbles

The ceramic diffusion plate produces bubbles so fine they look like white mist — which means more surface area per bubble, faster gas exchange, and less surface agitation that stresses timid fish or floating plants.
