Aquarium Stainless Steel CO2 Diffuser Atomizer with Integrated Check Valve, DC300-25

If the tubing slip connector with check valve hadn't been installed backward to prevent CO2 flow and wasn't jammed so hard onto the stainless steel tubing, it would have been a very pleasant installation experience. When I first installed and hooked it up, the bubble counter showed flow, but after a few minutes, the flow stopped. After reviewing all of the photos, I decided to reverse it because there appeared to be an obstruction and all the pictures show the thicker collar at the top. But pulling the plastic ring down while pulling on the stainless steel, it refused to budge. So I got some pliers after it and gripped the plastic ring and the connector and was able to remove it. Sure enough, when reversed 180, the connector easily slid onto the steel tubing and gripped it well. By pulling the plastic down and pulling up on the steel tubing, it was easily removed. After connecting everything up again, I can say it works well.

Best diffuser ive tried so far. Fine mist bubbles!

I like how this looks and it works great. The co2 comes out as a fine mist of bubbles.

Good quality. Like the design. Love the quick release and built-in check valve. Haven't had any issues. As long as you're using a pressurized system, should do great. Might present issues with lower-pressure or DIY systems.

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.

Works great. Very small bubbles. Works really well with diy CO2 system with yeast and sugar after the pressure builds up enough.

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.

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.
