Clscea Aquarium Stainless Steel CO2 Diffuser Atomizer with Integrated Check Valve for Rimless Tanks 40cm

I really love the quality, it creates very fine bubbles, I’d wish they made this model in nano size.

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.

Muy buen producto

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.
