The one suggested by amazon is too small .** A: This air stone matches two size air tubes, 3/16 " and 3/8". Wet the airline with water. It might be easier to install. **Q: What’s he material they use to make the stone?** A: Material: Mineral & Plastic. **Q: How many leters per min?** A: You’re better off with the pawfly 8” cylinder. These deteriorate extremely fast as if the material they used is insufficient. **Q: Do they sink?** A: Yes they do sink. Also check out pawfly 8” cylinders. I tried the synthetic pawfly black 8” and I think its cheaply made so I’ll be sticking with the original blue 8” pawfly airstone cylinders. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Right size for the job *by A***R on 28 April 2026* This product is not available easily in Indian market.
