## Questions & Answers

**Q: What size airline ? 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.

### ⭐⭐⭐⭐⭐ Great value and quality
*by K***Z on 21 July 2026*

Probably the best bubbler I’ve bought so far. I’ve tried the flexible ropes, the long bars, discs, etc and this one has lasted longer than all the rest combined. Decent size, great bubbles, and not over-priced.
