Easy to use and function well. Looks great in my tank and good with leakage of CO2

This system replaced my whole setup of glass tubes poorly hooking up to CO2 tubing and down into the tank where another poorly designed CO2 stone constantly fell off the tubing. The quality of this is exceptional and the ease with which it hooks up to your existing tubing is really outstanding.

I see all the other reviews of people having issues with the diffuser breaking. I have 4 of these now and have not had any issues with them. The wide bend tube fits nicely over the edge of my tanks with the plastic rim around the top. I have a 4-way splitter on top of my co2 tank with 4 bubblers giving me fine control and fine bubbles for all four units.

I've been using CO2 systems in my aquarium for a while. Typically opting for the plastic with cork diffusers, while they do the job they typically have leaks and from my experience become hard to upkeep with appearance.I decided to pick up CLSCEA stainless steel diffuser and it's a gem. Easy to install the connection points have a check valve and tube lock that ensure no CO2 leaks.I'm sure ovee time the ceramic plate will have algae and require some cleaning/replacement. But overall I really love the look. It does give the tank a little modern look so might not be for everyone but I think it really is a nice add.

I've had a number of different CO2 diffusers ever since I went live plants in my aquariums, and this is the best I've ever had. The steel is nicely made and the fact you can replace the disc is awesome. Inevitably I always have to do so and prior to this unit was always buying a new full diffuser. Hopefully those days are over!Really like the fact it is steel and not glass. I've broken glass ones in the past after cleaning and putting them back in the tank. This won't happen anymore. Yay!Good product. Highly recommend.

Despite what some other reviews have said- nah lol you definitely don't need an engineering degree or pliers to use this lol. The connection is push fit. If you're smart enough to figure out a finger trap you can handle it. I promise. Also it helps have to have the valve in the right direction. Theres a pictogram on the side showing the direction of unobstructed flow and obstructed flow cuz ya know its entire purpose is to stop water backing up from the other direction.Anyways- it works great. I've had it for over a year now. I love that the disks can be easily removed and swapped for cleaning. Its done well on a 29g and a 36g using a high pressure co2 tank. No leaks or blown outs. The bubbles are misty. It was undersized for a 75 but if you got the flow set right it would be usable for a large tank depending on your needs. I do wish that they offered just the check valve on its own though.

Will not produce bubbles except on the outer rim, no amount of tightening fixes the issue.

I’m a beginner in this aquarium hobby and this is my first CO2 setup. This product is easy to use, assemble and very aesthetically pleasing. 100% recommended.
