What Is An Airstone?

An airstone is a solid object dotted with micropores connected to an air pump. They sink down the water to ensure that the deepest part of the water receives proper aeration.

High concentrations of carbonate force more calcium ions to bind with carbonate, forming more precipitate on surfaces.

The Micropores In Airstones Create Smaller Bubbles, Which Increase The Surface Area Of Contact Between Water and Air

Oxygen exchange between water and air happens through the surface of bubbles. With more bubbles, you are effectively increasing the surface area of contact where oxygen exchange occurs.

What Are The Benefits Of Having Micropores In Your Airstone?

How Many Airstones Should Be Used In Aquaponics?

Dissolved oxygen allows fish, plants, and bacteria to respire and continue biological processes. Nutrients and chemical processes also consume oxygen in transforming chemicals to useful nutrients

It Is Important To Aerate Your Water As Much As Possible

You can not over aerate your system since most of the oxygen will always be used or evaporate into the atmosphere. A general rule of thumb is to ensure that each component that utilizes dissolved oxygen should have its own airstone. The main components that need airstones are the hydroponics unit, the fish tank, and the biofilter.
