Saim Flexible Airline Tubing for Aquariums, 20-Feet

Works for intended purpose. Ordered this one in June, I had ordered the same tubing back in 2016. Was confused when a different tubing showed up. This recent tubing is much more neon green then before, it's thicker (I didn't measure it but the pic I included shows a difference), and it's not at all see through like the first order. It does however look more like the pictures in the description, so maybe I received the wrong tubing the first order. I really liked the first tubing and was assuming when I bought it again it would be the same thing.Bad lighting but I included pictures with the tubing from both orders, the tubing from the 1st time is seen twice in the pic and the recent tubing is shown once. The difference is pretty obvious. When I first saw the difference I checked my Amazon order hx thinking maybe I clicked on the wrong one, but it shows I ordered the same product, so I included a screenshot of it.Tubing works, air stones distributing oxygen, just not the look I was going for, wished it was the same as the first order.

This works well in my tank, it definitely has a different feel than the standard clear piping but after several months it still works just as well and looks great against my black background!You can barely see them they blend in so well!Functional, inexpensive and does wonders for the cosmetics of my aquarium.All and all a great buy that is almost impossible to find locally for me.

This aquarium tubing has a lovely color (black with some shine but not too much) and is incredibly flexible, not almost irreversibly stiff like I have seen in some other brands. It is easily hidden by the black rims of my aquarium, easy to cut to length, and there isn't much hassle at all when attaching it to a filter/air stone/air source. Definitely recommended, and would buy again once I need more.

Thick walled, no kinks & great quality. Perfect for use with a reef dosing pump. Just ordered a different color too.

Great tubing. My husband siliconed it to the sides so it’s out of sight. He did this before we filled the tank.

Good tubing. It's thin and very rubbery but should work just fine. Took a while for delivery (came from China) smelled really strong like plastic or rubber, I washed with dawn soap and it's fine.

I like that the line is not clear. With the clear ones if there is a power surge or some other issue water can be sucked back into the tube which then causes alge to grow inside the tube.

Very thin and crimps easily. It isn't 100% black, more like a tint, so light will penetrate it (i.e. algae will grow in time).
