Air pumps

[Steve2223]

I have a dozen tanks from 10 gallon to 55, and I would like to set up one air system for two air stones per tank. Does anyone know of a dia. Pump that can handle the volume and pressure

Central Air Pumps

You'll need a airflow regulator to adjust the air pressure in each airstone.

Is there are reason you don't want to use a small linear piston pump?
