DC300-40

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.

Good micro bubbles! Its durable, fits, and cheap for the money. It does wonders. I'll attach an image. If you zoom it, you'll see the tiny micro bubbles it produces from my c02. Thanks

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 bought what is now a very popular CO2 Generator that many are buying and using in lieu of buying actual CO2 tanks. These CO2 generators are EZ to use and seem pretty solid as an alternative to actual tanks filled with CO2 . Anyway, these Generator kits Include the CO2 diffuser but they are cheap plastic devices which is to say everything right up to the diffuser itself which worked fine. The Ciscea diffuser was stainless steel and the actual ceramic plate that diffuses the CO2 was larger than the other I was replacing. Also, the Ciscea included an integrated check valve (very important to your CO2 system) and the CO2 generator kit that I bought while it included the diffuser system did NOT include a check valve. Anyway, both systems did provide fine and dense CO2 mist but the Ciscea was a larger disk so it provides more mist. For the price you cannot go wrong and replacing the original was EZ PZ fits right on to the tubing provided with the generator. I love it.

The diffuser works ,well ,no leaking ,the description was not clear about it would not fit a tank with any type of trim this is for a rim less tank I understand it to say some

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.

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.

Product looks great in the aquarium, but looks is not everything. First, try to find a replacement disc for CO2 service. The CO2 line fitting is a push fitting, the CO2 tubing is flexible and not hard. Leaks, you cannot get a seal with the tubing. Pretty but not functional.
