I finally got my 2213 and have a 5lb tank lined up. The hunt for a reg is on and I want to run my co2 inline. Based on what I have read it appears I need a 13mm one? Who has one thats considered "good" by the community?
I also like the Atomic inline diffuser, how ever its 8/12mm, 12/16mm, and i think they make another larger one too, but I am running DIY CO2 reactor, cheaper and I have a large cabinet to hide it inside. As far as minimalist and pretty CAL AQUA
29g Tetra Tank
100g Planted Angel/Clown Loach
I can't spell...Im an engineer, I do math
There's various brands of them too. UP Aqua makes one. I can't tell the difference in efficiency between either of them but the UP Aqua one is cheaper. eBay item 130812744574 is pretty much what you're looking for.
Silent at night, barely audible during the day if it's in a cabinet and adjusted right. Definitely quieter than an HOB filter splashing. With the Ista reactor, you won't need a 30+ psi feed from the regulator. I run mine at less than 10.
