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

    Works Great, Easy to Maintain
  

*by C***B on Reviewed in the United States on February 23, 2023*

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.

    Works and fits perfectly
  

*by A***H on Reviewed in the United States on February 26, 2024*

I have already used these to replace a clogged green one and they immediately start working so glad I have multiples so I always have what I need. You can’t go wrong. I have found if you are not using them they can clog with algae, because you havn’t made your co2 again they clog easily so love having new ones ready.
