Glass CO2 Diffuser U-Shape for Aquarium Plants

This is a lovely little diffuser! I bought two of them but have only set up one so far. It looks so clean in my nano aquarium with a neat little footprint. I love that the only pipe into my aquarium is glass and not flexible tubing. The bubbles are tiny and plentiful. I have only ever had one other diffuser before, and it was a Fluval ceramic ring diffuser. This is WAY better! Attaching the flexible tubing over the end of the glass tube is a bit difficult, but I put the end of the tubing in boiling water for a few seconds and was able to get it on without breaking the glass. Be careful, though - I saw where that happened to another reviewer, so I tried to be as gentle as possible. Overall, a good buy, and I highly recommend!

The tube connection is reduced so fitting standard hoses is easy. Not sure why other reviews stated otherwise. If using CO2 hose (which you absolutely should) just dip the end in hot water for 30 seconds. This was easy to install and creates smaller bubbles than my previous diffusers. The quality of this diffuser is outstanding. Just remember that it’s glass, so don’t be too rough with it and it will last you years. Just soak in bleach for a couple hours if it ever starts getting dirty or the bubbles start getting bigger. All diffusers require a little upkeep every 6 months or so.

I've worked with many diffusers in the past and understand they're delicate but this one snapped so easily when trying to apply the tubing. What a waste of money, and it's sad because it's a good looking diffuser.

Says it fits standard Co2 tubing, but:-GLASS IS THE SAME SIZE as standard tubing-no nipple to make the connection-to big of an opening to fit a line adapter inMine broke when I tried to put the next size of adapter in.This product would have been great if not for these hold ups. It is asthetically pleasing and I asume would do a great job, I just wish I could get my money back or a replacement so I could attempt to somehow jimmy rig it to work, but now that it is broken there is not much for me to do except warn all you.Edit:changed from 2 to 3 stars as I figured out what they were talking about. They mean vinyl tubing, not co2 tubing. I have an adapter hooked to co2 tubing to silicone tubing for an inch then it barely stretched and fit. You shouldn't use silicone Tubing as it leaks co2. This product looks very good in the aquarium, the connection is just poorly conceived and caused a lot of confusion and frustration.Edit 2: JARDLI reached out to me and offered me a full refund. Very spot on customer service, and now that all is said and done I add another star because the diffuser has proved to be very appealing and functional.

This is my 5th or 6th JARDLI glass product for my aquariums and I can say with confidence that this is an excellent product. The fitment, quality, and craftsmanship is great. I don't have anything negative to say. I mainly purchase high-end Japanese made products for my nature aquarium (ADA brand) but the glassware is the only place I skimp on cost because I don't see a reason to pay higher prices when JARDLI products have never let me down.Full disclosure, I have broken one of these CO2 diffusers because the diameter of the glass is very thin for airline tubing but I ordered another because I know JARDLI products are generally very good quality.

Giving it 3 because I didnt try to return. It did arrive fairly quick. So the glass work and bend is do!aqua quality, however like some others I put 60psi through this guy since my 40psi wasnt working, 50psi was a no go and so was 60psi, gave up since i didnt want it popping. Tried washing it with everything from vinegar to a 50/50 acid solution. Oh well at least it wasnt much.

I have no idea how people can downgrade this diffuser since is perfect!!! Style, good fit, excellent bubble disusing stream, while is true is made for rimless aquarium, you can cheap the rim just a bit for the U to fit over the tank. Not only will keep the diffuser steady, but you also do not need any additional suction cups. Most complaints seams like are related to the co2 line breaking the diffuser. Really? You do not need a hammer to install a co2 line in a fine piece of glass.

Looks flawless performance is great. Mine was defective but I wanted to try again because I loved the look and got a replacement and I was not disappointed. These are extremely delicate. Especially around the curved parts. Other than that great Co2 diffuser couldn’t be happier.

The diffuser itself looks great and came quickly and was packaged very securely! The only issue is, I bought 4/6mm tubing like it said in the description, but its VERY difficult to get on. I haven't been able to get the tubing on to the diffuser. The hole of the diffuser looks the same as the hole of the tubing. I bought this knowing the reviews said it is very difficult to connect to tubing, which is why I gave it 4 stars. Hopefully I will be able to connect it and update this review on how it works.UPDATE: I tried putting the tubing on and if you just dib the tubing in boiling water for a couple seconds it goes on quite easily. Definitely changing this to 5 stars! Came fast, looks great and works how its supposed to.

Bought to replace suction cup diffusers i keep having to reattach I use in the pump compartment of my flex, working great so far, followed instructions as to let it soak for 10+ hrs before hooking up co2 and yeah so far so good
