Review on 🐠 Penn Plax Deluxe 20 Feet Silicone Flexible Airline Tubing for Aquariums, 3/16-Inch by Danae Velasco

I thought it would be very flexible and flexible - like surgical tubing - like hypotube. It is not. It's only slightly more flexible than standard vinyl channels. I wanted a really flexible hose that would easily straighten out under the weight of the air stone so the air stone would naturally fall to the ground and stay there. You know the problem - vinyl tubing is stiff and any kinks or kinks stay that way, leaving the vent just arching off the floor - so annoying. Well this silicone tubing doesn't solve that problem so you can save money and buy regular vinyl. Also, I'm wondering if it's really silicone because it looks more like vinyl.
