Saim Flexible Air-Line Tubing for Aquariums, 20-Feet (Black)

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.

Very soft and flexible, strong, and goes back into shape if stretched. Provides a very tight and strong connection to pumps, accessories, valves, no leaking, no accidental or unintentional disconnects. Good for tight spaces and sharp angles that are problematic for less flexible tubing with thicker walls. Arrived tightly coiled with smashed ends, I uncoiled it, recoiled it very loosely, hung it on a hook, and within a few hours, no kinks, no smashed ends, no flattened areas or imperfections of any kind in the entire length of tubing. It naturally wants to go back to its original shape and size. If this describes your intended use, I see no reason why this tubing wouldn't serve you well. If wall thickness is more important than flexibility for your set up, then maybe this tubing isn't for you. For me and my needs, this stuff is ideal.

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.

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.

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.

way to flimsy. It bends over on itself and does not allow the air to flow through. Since I cut it for use, its not returnable, but it's rather useless.

Great product if you have a dark background and don’t want to use the clear/white airline.no more airline showing in the background will be buying more

White powder stuff on it under water
