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

The media could not be loaded.  I really love the quality, it creates very fine bubbles, I’d wish they made this model in nano size.

The media could not be loaded.  Creates a fine mist of CO2, works perfectly. Top quality product. 👌

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.

The media could not be loaded.  I spent hours trying to figure out why bubbles are not coming out, and it worried me all day. I thought that something was wrong with my CO2 generator or my tube. It turned out that this product was simply not working the way it should which created CO2 leak.

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.
