Aquarium CO2 Proof Tubing 16 Feet (Clear)

This is fine hose. It fit all my fittings and it’s not as stiff as some have said. Yes it’s a little stiffer than cheap airline tubing, but it’s nothing to worry about. It’s specifically designed for c02. Don’t let the other reviewers scare you away, like they almost did me.

Pros:Extremely durable, does not leak, does not tear or develop pinholes like softer tubing, can be made more flexible with heat, fitting will not leak or come apart once installed.Cons:Not very flexible, need to use a drop of oil on fittings to get this tubing onto the fittings, must be extremely careful if installing onto glass fittings as the pressure to push tubing over fitting can be enough to break the glass.

Worked perfectly for my freshwater aquarium’s CO2 system! The CO2 hosing is a stiffer material then standard air-line hose, so you need to heat the end of the hose slightly to fit it onto the fittings. (I just use my DeWalt cordless heat gun on low.)I purchased the 25’ length. It came with multiple suction cups to run the hose inside and on the outside of your tank. Would buy again if ever needed.

Cost effective tubing that is functional for its intended purpose. Good material and doesn’t take away from the beauty of the tank with the clear color.

Works great! Not prone to back leakage, handles pressure well, and fits all diffusers I’ve tried.

"Attractive" Crystal Clear material. Flexible enough.Bonus: 5 High quality clear suction cups included. (I only needed one in tank). They stick very well.

Can't really say much of the product except that it works as intended and the quality of the materials used is good. Some "CO2" tubing I have purchased in the past is flimsy, it is not the case with this one.

I used this tubing to replace some cheap airline tubing that I was using previously. The old tubing wasn't CO2 proof and it was apparent. This tubing is 100% CO2 proof based on current performance. It's much stiffer than airline tubing which makes installing it a bit more tricky, but not too bad. When I turned my regulator on I set my bubble counter to 1 bps (bubble per second) and holy cow! The CO2 output into my tank looked to be probably three times as much gas as I had seen coming out of my diffuser when I used my old tubing. On Airline hose, I lost 100 PSI in three days and my PSI almost didn't move after running this CO2 tubing for 3 days at 1 bps showing that this is much more efficient. (Yes, I know BPS isn't exactly an accurate measure of flow but its the best I've got)
