08-08-2025The tubing does it’s job well. I run sponge filters off of a Top Fin air pump. The tubing, however, was extremely difficult to fit over my air pump output, my check valves, and my sponge filter. In comparison to the brand of tubing I used before, this one had a way smaller inner diameter. I had to hold the tubing under hot water for a while in order to jam it over the outputs.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.
