Choose Between Standard and Deluxe Airline Tubing
Our Aquarium Airline Tubing offers a great solution for various aquarium airline needs, such as connecting an air pump to an air stone, an under-gravel filter, or an aquarium ornament. They’re designed and tested to be safe for freshwater and saltwater tanks.
Standard:
- Comes in 3 lengths: 8 feet, 25 feet, and 500 feet. They’re made from durable plastic that’s ultra- clear, which virtually disappears when in water. This tubing is resistant to cracking, and should provide months of maintenance free use.
Deluxe:
- Comes in 3 lengths: 8 feet, 20 feet, and 200 feet. They’re made from flexible silicone. The light green hue also virtually disappears when in water. This tubing will never harden, crack, or kink, making it the easiest airline tubing to use.
Having Issues Connecting to Aquarium Accessories?
- For better connection, soak both ends of the Airline Tubing in warm water for 30 seconds. This will allow the ends to stretch more when connecting with a tight fit.

There was a problem filtering reviews right now. Please try again later.
So I used it to siphon the water instead and works great. Price i got it for makes it an easy 5 star
The price can’t be beat and the tubing works great after the initial struggle, but if you don’t mind spending a few more cents for ease of use, pick a different brand.

I had to use a bit more force to fit it into some of the accessories (compared to when using my other tubing), but after that there was no problem. To me it’s not that big of deal considering how cheap the price was.
In the pictures you can see this item is the one that has a smaller diameter.
