LDEXINAquarium Flexible Rubber Wall Air Curtain Bubble Tube for Fish Tank Soft Rubber Tube Hose Oxygen Diffuser Tube 75cm/29.5“ Length

it comes folded.hoses are not supposed to be folded .the folded parts ripple and make the hose bubble unevenly ,no matter what you do.also the second one I bought came with both ends clogged (by glue) and had to drill it with a small drill to open them . if they fix their quality checks they will provide a good product .

They do work very well, but I do wish they would have put suction cups with the wands.

I use these for a small hobby type of hydroponic set up. I got tired of the stone type plugging up and stop working. I am hoping these last longer than the stones and so far is working well. Not concerned about how it looks vs function. This review is my second order of a two set as pleased with first order.

The title says it. Save your money.I thought the flexibility of these would be cool for corners or shapes in the aquarium. Nope. They don't really keep a shape. They also don't want to stay in the water. I've bought extra suction cups & tried alternatives for anchoring. They float up to the surface any time they get bumped (I have cichlids). Side note-the material they're made of also gunks up really fast, making cleaning & reattaching a total hassle.Basically, I've ordered a "traditional" bubble wand & will be replacing these out when the new one arrives.

Actually very flexible. However trying to bury it is horrible. It bends well, but I have had trouble trying to bury it under the gravel in the rear of my 60 gallon tank; when I poke one end down, the other pops back up.

I never used this for my project because it didn't perform very well. Regular stones work better.

Works very well. I have a 50 gal tank and put both in. They give sufficient bobbles.

The media could not be loaded.  I wish they connected together to make one long one. But I got a second pump (you could use splitters) and I love all the action the bubbles add to the tank!
