Hi,

I purchased this kind of co2 set from my local seller. But I dont know how to install/add the bubble counter onto this system. Because the way it setup so different, the co2 tubing is under so I cant find the way to add the bubble counter. What should I do?

This figure is bubble counter i want to add:



Here is the co2 system with solenoid:

It is doable, but based on your question, I am guessing that you have limited experience with co2 rigs.

My advice: Save yourself a lot of time and headaches and install an in-line bubble counter, just splice it into the green co2 hose.

Hi OVT: I known that option as well, but I just want to know what the other way if that is possible? Maybe the setup isnt good for that kind bubble counter?


I also found online same kind with bubble counter simple added, but is this the only way can be?

You'll need an elbow, a tube extension, and a tube adapter. I wouldn't bother as that's going to cost more money than you'd want to spend. As well, BCs look ugly attached to the regulator assembly. Hook it up in-line like in the picture.

I totally agree with the tube extender and elbow. A local welding shop should have the fittings that will work for a reasonable price. I purchased most of my stuff from a welding shop. Once you get the right fittings...you 'll have a nice setup.

Your final setup should look something like this: http://greenleafaquariums.com/co2-regulators/supreme-co2-regulator.html

you guys do realize that the valve is not a true compression fitting right? it's a barb with a nut to secure the tubing. I can't think of any way to hard plumb that to npt ports without doing something custom.

just screw a 1/8 npt x 1/4 od push in fitting on the bottom of that jbj bubble counter and you can run it inline. pm me and i can send you one.

Good point on the compression fitting, missed that.
Thanks Neil

And while you are moving the bubble counter so that it is not right above the reg, etc., look for a spot totally away from those. Once you put it inline, you have lots of options for making it better. One is not to put it directly above the things you want to keep dry! Dumb move to put the liquid so it immediately runs down into things if the check valve fails! So once you have it on tubing, you can also put it where it is not so likely to get broken and also where you can see and reach it real easy.
Good to move it and certainly worth the trouble to find fittings.

The bubble counter in the first post will screw right onto that needle valve. That's what the o ring that comes with those bubble counters is for. All you'd have to do to add a bubble counter would be to reposition the needle valve so it's flat and there's enough room for the counter to clear the regulator.

so the threads we find on nv's for aquatek/milwaukee/azoo/jbj etc are 1/8 npt threads? I've always wondered how the ebay sellers did it :p

Not exactly the same. The threads aren't tapered like npt but it is still enough to make a seal.
Good to know, so it can be done after all.
You guys are such a good resource , thanks for sharing your knowledge.
Regards
