Have used this course airstone for years! Big bubbles, great for fresh or saltwater tanks. Fish love to play in the bubbles, and they help to move the water to create more oxygen! Glad I can still get them cause they're getting harder to find!
I use these. More simple than normal air stones and the course setting, the air pumps don't have to work as hard to get a bubble and water current flow going.
