Glass Inline CO2 Atomizer Diffuser System for Aquarium Planted Tank (13mm for 12/16mm (1/2" i.d.) Hose)

================================UPDATED/NEW REVIEW================================I am updating this review of the Glass Inline CO2 Diffuser on 20 October 2017, and I am highly impressed with JARDLI willingness to listen to their customer and implement the feedback. Furthermore, their customer service is top-notch that goes the extra mile by quickly contacting me via email that they wanted to implement my feedback in their next production run. My gratitude shows by updating my review with the newest model! Please read my old review below for more information what previously occurred with the old model.WHAT CHANGED?I was sent a test model that increased the tube connector length, and I did a two weeks test run to assure that the tube connection stays secured without needing clamps or zip ties. The increased length allowed more flexibly where the tube can bend just a little bit and still maintain a firm connection. I was so impressed, and I feel that I will never see another aquarium flood! View photos to see the difference! I cannot express how much of a difference the increase length made, but it made a huge difference!THE 1-STARS REVIEWS:I read the 1-Stars reviews that stated that the glass is weak, and I find that false. With any type of glass, it should be handled with great care. In addition, if using excessive force to connect the tube connector to the point that shakiness occurs, then of course the glass will most likely break or crack under pressure. I highly recommend to soak the tube in a bucket with boiling hot water for about 15 minutes and cover the bucket with a thick towel. Afterwards, the tubes will be soft enough where a light amount of force is needed for the tubes to slip on and when the tubes cool, it will create a tighter grip. The tighter grip will not be so tight to the point that it cannot be pulled off. Lastly, I was very surprised when reading those 1-Stars Reviews.EXTRA NOTES:I was going to create a video, but I saw that the photos were more accurate than a 1 minute rambling video stating the same. Photos are worth 1000 words, and it clearly shows the difference between the new and old models. Also, with just 4 photos, it is quick and easy to make the decision to purchase :)================================OLD REVIEW================================I purchased this item on July 15, 2017, and I am posting a review on August 30, 2017.Pros:+ Very strong glass+ Diffuses CO2 exceptionally well+ Easy to cleanCons:- Short Tube ConnectorBe warned that I highly recommend purchasing CLAMPS or Zip Ties when attaching the vinyl tubing because the input connector is to short which does not leave much room for error. As a result, I came home today on August 30, 2017 to find I had a flood in my living room because the tube connected to the bottom of the diffuser slipped off. Luckily, I have vinyl floors in my living room.The product is great with one major flaw which is why I gave it a 3/5 stars. Please be advised, if you purchase this product, then get clamps or zip ties to tighten the tubing to avoid a disaster like I did. If the company increases the tube connector length to allow for the tube to grip better, then I would redo my review and give it a 5/5 stars.

Arrived on time, well packaged, exactly as pictured.Previously to ordering this diffuser I was using a fairly high end, more traditional "in the corner" diffuser that required an airline to go down into the aquarium to deliver the CO2. On this airline I had to place a separate "Bubble Counter" to be able to determine the relative rate at which CO2 was being delivered into the tank. That old diffuser tended to get coated with algae over time. I guess my Plecostamus did not like eating while surrounded by all those bubbles.This inline diffuser:1) Eliminates one airline going into my aquarium. This makes it easier for me to move my hood that houses my lights and covers the aquarium.2) Will not get full of algae as it isn't under the aquarium lights.3) Seems to do a better job creating many tiny bubbles that dissolve better in the flow of water returning from the canister filter. The "In the corner" unit produced streams of bubbles that made it to the top of the water and burst letting more CO2 escape. That would be ok if it was delivering air, like an air stone, but I'm paying for that CO2, I don't want to waste it.4) The "Bubble Counter" feature is built in since the CO2 chamber never completely gets rid of the water that got in there during set up. That might not be obvious by looking at the picture. So that's one less item you will need if starting with this kind of diffuser.As always, with glass, no matter how strong, there is always the possibility of breaking off the CO2 delivery arm. I use the extra flexible tubbing that my fish store recommends for CO2 lines. Even then, I still use something like the point of a pencil to stretch the line a bit before trying to get it over a glass arm.

This diffuser is awesome it doesnt leak like so many others. Initially i was so scared of buying because I've never dealt with glass equipment and i was so scared of breaking it ,but it turned out to be preety sturdy I had no problem at all with the co2 arm when connecting the co2 tubing I just warmed it up in hot water(tubing) before inserting and it was easy you would have to be pretty rough with it to break it. Best of all it does a great job at diffusing the bubbles all over the plants in my 29 instead of the intank diffuser I had where only half of my plants were getting misted. I'm very happy with this and would recommend

Why did I waste so much time on other inline diffusers???? This was the easiest and most effective (not to mention aesthetically beautiful). I had a plastic one before and the c02 busted the seal after a few years. So glad I finally gave up and ordered this one.My plants thank you!

Great build quality. This diffuser functions as it should and looks great. On top of moving the diffuser out of the display, this style seems to better disperse the CO2.

Pretty solid piece of glass. No worries of it breaking that easy. (As with any glass product do take precautions). Just be careful when installing the co2 line. I had to heat the co2 tubing slightly to slide it on to the co2 input line. Other than that its a pretty good item. Does not leak and simple in construction. This diffuser just has that classic retro look to it which in a way attracted me to it in the first place.

Im the first to leave the review. I have had 2 other products to mix co2 and has been very very unsuccessful. The product cracked and leaked.This one is the best no leak and clean. Mixes way better and best of all no leaks. It is glass hence need to warm the tubes before inserting.EXCELLENT!!!

The bubbles didn't all completely dissolve before entering the tank, but I'm sure it made the diffusion of CO2 into the water better.
