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

I boiled a medium sized pot of water and dipped my length in it for about 30 seconds and let it hang until cool. This will get the creases out of the packaging, it really doesn't crease. They look a lot less manufactured. They work great. I wish they were greener. They're more of a blue-green color, so don't mix with plants.

My old clear hose became so stiff I hated working with it and had to cut off some of the connectors. It's so flexible yet holds tight to any fitting. I love the color too. It looks more like a teal and really disappears next to some greenery in the aquarium. It has an odd smell that doesn't wash off, but the fish don't complain.

It was very difficult to attach via the barbs to the items it was meant to connect. (pump, air stones, check valves, etc.) This tube met and exceeded all of my hopes/expectations. Went like clockwork. If there are long term quality issues I will update my review as I do with all my reviews. Although it is necessary at the…

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…
