Suggested for using in the adoption of the Nano bubbling method.
Natural micro-pores in limewood create incredibly fine bubbles.
Limewood gives a finer curtain of air bubbles than normal airstones in salt water (also suitable for use in the freshwater aquarium for a finer bubble display.)
Perfect for use in air driven nano skimmers and foam fractionators. Can also be used as a premium airstone in any aquarium due to the sheer volumes of microbubbles limewood airstones create.
Highly durable limewood which has been long matured.
