🐠 CORISRX BEST OF YOUR LIFESTYLE Airline Tubing: 20ft/6m Co2 Tube for Aquarium CO2 Systems Review

Excellent hoses. I use it for my aerators in 300 gallon aquariums. It's long enough that it can be cut in half to get to the center of the tank. I recommend it.

The hose fits easily over the regulator, bubble counter and diffuser nipples, but is very soft and kinks easily, causing kinks in the line. That works, but something more permanent is needed for the various connections of the CO2 system.

This is NOT a CO2 hose as advertised. This is clearly regular airliner silicone tubing. And for what it really is, it's way overpriced. Yes you can use it for CO2 like you could use any other aviation tube but that doesn't make it CO2 resistant. Silicone is highly permeable, allowing carbon dioxide to permeate through walls while losing up to 30% carbon dioxide, possibly more depending on length. I wouldn't trust such a soft, thin-walled hose to withstand the pressure of a carbon dioxide system
