4 x 70mm Air Stones – Blue

Aeration for Aquaphonic and Hydroponic systems is absolutely crucial, especially if you are utilising Deep Water Culture (DWC) units.

In densely planted channels, the oxygen demand required by the plants can cause the Dissolved Oxygen (DO) levels to drop below the required minimum level.

This can have a major impact on the plants and is therefore critical to ensure regular air flow through the system.

In order to ensure aeration, it is vital to place air stones in the system which is connected to air piping through which air is pumped from the air pump.

These are high performance cermic air stones containing lots of pores in order to produce fine bubbles which in turn provides excellent oygen for the water.
