It's about time to setup my reactor. I have a few questions and MRC hasn't responded yet so I thought I'd ask you guys.
The tubes that hold media I assume need an 0 ring on the top of each. I don't have em and need to know what size they might be. Also my second stage tube has a connection on the top of it that looks like a way to plumb an RO to it. If this is what it's for I'm not able to do it if it isn't what it's for I'm not sure how it all hooks up. I downloaded his instructions from the site and his drawing but it seems slightly different from mine. Also when everything is hooked up the way I think it needs to be hooked up I open my cylinder bottle up and it just blasts co2 out of a hole in the side of the regulator and makes a horrible whistling sound. What do I do about that?
I can upload some pics if needed.

Hey Samper,

OUrs doesn't have any O-rings but does have like a cloth type of "washer" between the tubes and the lid. It is pretty thin though, not sure how useful it is or if it is even needed.

Not sure about the RO fitting on top of the second chamber, ours doesn't have this??

On the whistling, I went through the same exact thing. If I remember correctly you have to open the valve on the gauge and then open the tank.
