Hello everybody!
Recently I've bought my CarbonDoser on the secondhand market but almost (or completely) unused. But I've met a problem. As I'm from Ukraine and I've bought the regulator from the USA I can't connect it to my CO2 tank!
On the tank the thread is DIN 477 (W 21.8 x 1/14") and on the regulator - CGA320 (0.825" - 14 NGO). And there is no adapters!
I've been contacting AquariumPlants to buy a new DIN-sized nipple for the regulator for monthes, but no reply. They are simply ignoring my mails!
Does anybody have an idea where to find an adapter or new nipple for this regulator?
Or maybe someone knows who is the maker of the CO2 regulator used in the CarbonDoser? What is the thread of the nipple (where the nipple connects to the regulator body)?
Thank you in advance.

ivans, jump on ebay and search for DIN 477. There are hundreds listed. The first thing that came up is 1/4" NPT on on side, DIN 447 on the other. I believe all of the adapters are 1/4" NPT on the regulator (what you posted above, the GCA320 specs, 0.825" - 14NGO is probably 1/4 NPT). Anything for Aquarium CO2 is going to basically expect you to be using the same equipment.
I believe all of the USA regulators are 1/4" NPT. It certainly seems that way from the description of all of the aquarium plant CO2 regulators.
You just have to get a socket or wrench to attach to the GCA320 tank-side nut, and unscrew it out of the regulator, then put the DIN 447 adapter into the regulator in that same slot, and you should be good to go for EU gas.
The CarbonDoser is mostly distributed by AquariumPlants.com, and I've called them with some basic questions before and they've been mostly helpful (though they're not regulator experts).

Will this Regulator work
Will this Regulator work
I am in the process of switching over to a calcium reactor for my tank. I have a geo reactor, masterflex pump and the last part is building the CO2 Reg. I just purchased a regulator and now I am having buyers remorse because I don't know if it was the right one or not. Oh well its mine now. Hopefully it's the right one.
It's a Matheson Stainless Steel MREG-4610-SA. My worries are the max inlet pressure is 3500psi. I am also worried that it may or may not be a dual stage. Can anyone verify if this regulator is the right one and will work? I'm in it for 90 with shipping.

Brass will polish up nicely, however it will tarnish if put in the stand near your sump. Also, while all of these choices seem nice, make sure they have a return policy so that you can perform a proper leak test to make sure the internal duaphagm is not damaged and there’s no internal leak.
For leak test procedures, see post #12 of this thread.

Does anyone know if this needle valve will work? I can't find if it's low or medium flow.
SS-ORM2-S2
It says it has an orifice of 0.080 in. Seems like it may be a low flow.
Thank you all for your help with this. Can't wait to get the carx melting some media!

I know the ss-s2 is a low flow. So I'm hoping.

So I bought the med flow meterign valve and now I can get a slow steady bubble rate. The best I can do is a couple of bubbles a second. The valve has to do the lifting until I can find a low flow valve for a reasonable price. If anyone here has one let me know.
When I change out the Metering valve I'm getting rid of the on off valve. And then braso and a sealer to keep it shiny!

Anybody have any information on how to decipher a regulator model number? Particularly the older Airgas models. Trying to determine by model number the body material and working pressures.
