This is what I'm running, the regulator comes with PLASTIC O rings and I just used that with no leaks yet but metal rings are worth it. All you need is regular air line tubes, the diffuser is up to you and you should do some research on those aside. And I would buy a metal check valve not a plastic one.

Actually you need to get line made for CO2. Regular air line deteriorates from the CO2. Even DIY CO2 will erode regular air line. You will eventually get holes in the line. As for diffusers you can get glass diffusers that come with a replaceable ceramic disk. The CO2 eventually clogs up the disk so it is nice to be able to replace just that part. You can also get this type of diffuser in plastic. They are almost invisible in the tank. You can also buy just a small powerhead like this Azoo Powerheads. You can also get inline diffusers so you don't have to put anything in the tank. You will need a bubble counter and a drop checker too. A metal check valve is a must also.
