Well I’m so glad a friend of mine who’s super experienced with planted tanks recommended this brand. Not only is this regulator way more affordable than others but the product is pure quality and comes with all the features you want with a high end regulator. Super easy to set up, twist it onto your co2 tank, push on your co2 tubing and push the other end to whatever diffuser you’re using, plug in the regulator, twist on the co2, get the bubbles per second you want and boom, or should I say done, no pun being intended. For me it was especially worth getting the pro model so that I could have the dual checks to stop any end of tank dump and protect my fish. I spent way more than the difference between regulators so why not spend a little more for the peace of mind. It’s also super aesthetically pleasing. Also, I wanted the option to be able to move the regulator around to different tanks if I wanted, particularly multiple 10 gallon grow out tanks I set up in the garage (with the families blessing lmao). This regulator lets you add modules so you can run multiple co2 lines to multiple tanks so you’re not having to get some splitter to attach onto a regulator which would just be opening yourself up to more issues rather than just getting a regulator from the start that allows you to add modules and grow into. I already moved mine from my 55 gallon to my 6 grow tanks and am just going to pick up another regulator. The only downside is you might end up with a few more tanks like me but even friends outside the hobby appreciate seeing 6 grow out tanks that end up looking like dutch style rainbows or epiphyte jungle scapes with the help of co2. I have a near embarrassing amount of houseplants but aquatic plants still blow me away. It’s definitely a game changer, both co2 and having a regulator that is jammed pack with these features. Oh and I recommend just going to your local homebrew store and picking up a 10 lb co2 tank. It looks absolutely incredible with the regulator and it lasts forever. It beats the crap out of anything else on the market both above and below it’s price point. Last thing I’ll say is to the people who are thinking about taking their first steps into co2. Do it. It takes a humble yet beautiful fish keeping hobby to a place where you and your fish are so so much happier. The sheer ease to which you’ll grow plants will make you feel unstoppable and your fish will color up, display brilliant natural behavior and you’ll just get so much more satisfaction seeing an underwater world that you just want to cozy up in or go explore. Anyway, this regulator knocked it out of the park for me. Great company, great selection and dope product. Dang didn’t mean to write so much but I’m friggin pumped.

Works so well and feels high quality, good bang for buck. The solenoid does fully cut off co2 to the diffuser when it is powered off and there are no leaks. The needle valve is kind of sensitive but it allows for fine control and has been holding steady bubble count once set. Fzones support system is amazing too, as they assisted with all my questions in short amount of time and was willing to stick with me until the problem was resolved. I would buy from fzone again just for their support system alone.
