Review on 🐠 Lee's Aquarium Thinwall Rigid Tubing - 6-Pack: 3/16" x 3', Durable and Versatile by Amanda Smith

Many reviews have said this is the right size for a standard aquarium tube. I wanted a nice and clean airline for my tank and this brand seems to be what I need. I took out my calipers and started measuring the air stone and air pump fittings and hoses. The sizes didn't seem to match, but I thought I misunderstood the inner and outer diameter measurements of the product. Now that I have it in my hands I can see that the OD of the rigid tube is designed to fit the flexible tubing that came with your air pump. I thought the intuitive approach would be to connect a hard hose directly to all your stuff - you can't. You will need to make adapter connections by cutting small sections of air tubing. Also, mine came in a nice long box - no bent tubes. Mine comes with a free Prime option.
