Just look at nearly every place of business that sells fish. If they keep their water systems segregated, they will be using these. One can easily run 3 units from one air supply. If you have and extra-large air supply, you could run significantly more. No moving parts. Nothing to break. I use the diffuser stones that fit inside the unit and the bubbles are tiny and really look nice as well as help oxygenate the water better.

Written for the common man.
Very easy to read with common-sense kind of vibe. Not "advanced pointy-head" type.
