needle valve

  1. Equipment
    I have a CO2Art SE two stage regulator with the included bubble counter and needle valve. I thought my valve settings were getting jostled as I dial in this new tank and mess with the systems, but I believe at least one issue is sometimes the CO2Art needle valve will generate a different bubble...

    I am selling a 5lb co2 cylinder with an attached dual gauge regulator by Red Sea with an attached needle valve,long tubing and 2 co2 diffusers. altogether for $90.00. I can only do "pickup only" with these, and I'm in Elizabeth NJ. Payment is by cash only.

    I managed to knock my needle valve so I have had to reset the bubble count to approximately what it was before. Say I put the bubble count too high, how long would it take for CO2 to build up to a point where it could harm my fish? Thanks :)

    Hey guys! I have a dual stage Victor brass regulator that I am selling, as I would like to go with stainless steel >:).

    I need to get a new o-ring to go between the standard CO2Art needle valve and bubble counter. I've tried searching around, but I can't find what that size of o-ring is called. Does anyone know what that size of o-ring is called and where they can be found? If necessary, I can order a new one...

    I have found out a website where you can calculate the flow (Q) in scfm (standard cubic foot per minute). But to do that you need to fill in some data first: 1) Cv (flow coeficient) 2) Upstream Pressure 3) Downstream Pressure 4) Temperature 5) Specific Gravity for your gas ("Carbon Dioxide" in...

    So I just got my first CO2 set up used from my local fish club. I jumped at it because it was a good price, but now that I've actually got it, I am beginning to second guess my purchase. I knew that the bubble counter was broken when I bought the unit, so today I went ahead and bought a new...

    Hey guys, I am building my custom CO2 regulator and looking around for parts. I am lucky enough to have a Swagelok distributor in town (gotta love Portland, Oregon!) and, since I wont have to pay any shipping costs, looking very closely at their needle valves. It sure aint easy trying to...

    Hi all! Today I had an extremely productive trip to the local airgas!

    Hey, I just received my fabco nv-55, and I'm a little confused about the holes in it. The holes in the sides are where I want to attach barbs / tubing / check valves / potatoes, right? What do I do with the hole in the bottom? Do I plug it? Or is that where excess pressure is vented? Isn't...

    How do I know? It's not my knee. My C02 levels have never been as constant as I would like (BBA). From time to time I notice my reactor would cavitate(sp) / burb and, in the worst case, my fish would be up near the surface gasping by the time I got home from work. I started noticing that...

    So, while I'm waiting for the big tank to grow in an emersed setup, I figured I would use my CO2 cylinder that's just sitting there and hook it up to my two 10gal tanks that were previously on DIY setups. I had everything setup and I turned on the CO2. Didn't see any bubbles so I cranked the...
