Air Stones - 4 types

An air stone is a small porous device connected to an air pump and placed in a water tank or aquarium to aerate (oxygenate) the water.

It helps keep it clean and clear, helping circulate the oxygen, resulting in less algal growth and generally healthier plants (and fish).

Air stones need to be connected to an air pump to work.
