Review on 🐠 Pawfly 1.6 Inch Hydroponic Pump Air Stone Bubble Ceramic Diffuser for Aquarium Fish Tank - Set of 4-8 PCS by Kim Marshall

Revainrating 5 out of 5

Can be used at low and high pressure for small bubbles. Works best lying face down

Produces a consistent amount of bubbles; Low air pressure creates very small bubbles, while high air pressure creates large numbers of 1/4 inch or smaller bubbles. High pressure (20-40 gallon air pump) creates a strong surface disturbance and some local flow in the 20 gallon length. Seems to work more efficiently when the bubbles exit straight up.

Pros
  • Consistent results when tested
Cons
  • Mostly fine, but...
