Air Stones

Air stones are porous elements that are installed in hydroponic system tanks or substrates using air (from a pump) to increase oxygen access to the roots. They create microbubbles that improve aeration, prevent water stagnation and reduce the risk of root rot. They are suitable for DWC, NFT, EBB & FLOOD and other soilless systems. Suitable for use in aquariums and for Aquaristik.
