タイトルまたは説明

Air stones break the stream of air produced by your pump into thousands of tiny micro-bubbles, which add a healthy stream of bubbles to your aquarium. Sandstone airstones can be used in fresh or saltwater aquariums. Multiple stones can be connected together. This long-lasting sand stone aerator will add beauty to your fresh or saltwater aquarium.

 They also keep those fun, whimsical action ornaments running to amuse you and your fishes.
