Review: Works great. Can make lots of small bubbles and they come out evenly across the entire stone. Doesn't make a lot of back pressure straining your air pump. I wish they made even longer ones this style from this company. Other long straight air stones I've tried require more air pressure.
Review: Used these for airation in my aquarium sump for a fluidized bed reactor. Works amazing. Surprisingly small bubbles wich is great, and these don't float which is perfect. Highly recommend these. You do need a big air pump to run these

## 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.

### ⭐⭐⭐⭐⭐ Review
*by G***Y on 18 October 2025*

These work great, love the 2 pack. Standard aquarium tube slipped on and held very securly. Very heavy and solid feeling. I put one in my shallow well and one in my settling tank, puts out a lot of air and i only have like a 18 watt 120 pump! If i ever need these again i will get them. They do sink! I know some people had issues with that, but i did add mine on a line with a weight so i can adjust the height in the well. Good solid product. Reccomend
