## Description

desertcart.com : ALEGI Air Stone Cylinder Bubbler, 5.3 inch, 2 Pack | For Hydroponic Systems, Aquarium, Fish Tank : Pet Supplies

Review: Great value and quality - 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.
Review: QUALITY AIR STONES - 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.

## Features

- 5.3 Inch airstone needs the air pump of at least 4W.
- Measures 5.3-inch long by 1.2-inch diameter. Uses either 3/16” or 3/8" inner diameter tubing. Net Weight 0.33lb. Strong shell to protect the air stone.
- Soak the stone completely in water over 2 Hour before use. Clean regularly by a brush as they get clogged.
- Suitable for aquarium, fish tank and hydroponics.
- Comes with 2 Pcs Grey Cylinder Air Stones.

## 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.

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.

### ⭐⭐⭐⭐⭐ QUALITY AIR STONES
*by M***C on December 17, 2025*

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.

### ⭐⭐⭐⭐⭐ Better air dispersion that stays submerged
*by S***G on May 31, 2026*

These have substantial weigh so they stay where they are placed and the air is disbursed into the water better than other stones I've tried.
