Thanks,I'm researching regulators still . Here is one newbie observation. A lot of what I am seeing considering most price ranges and your early recommendations; Single stage regulators: Cornelius, Micromatic, Victor as well as; Dual stage regulators: Concoa, Matheson and Victor, most have horizontal bottle mounts and this makes no sense to an old - old -school welder. I don't want sideways gauges! What's up with this?
I've gone back to looking at the single stage regulators for cost savings.

I'm not sure what you mean by horizontal bottle mounts/sideways gauges. The gauges can be rotated, as they are simply threaded into the regulator body. Unless you are referring to the text not being parallel to the ground?

Yes the gauges text position. My acetylene tank has a horizontal mount which makes its gauges sit correctly, whereas the oxygen bottle has a vertical upwards facing connector and its regulator and gauges fit on top. I hope that made sense.

I'm not quite sure what you are referring to; here is an example of a CO2 system I set up a few years back.



The next is readable, albeit not precisely parallel with the floor. However, once you set it, there's not much you need to do; unlike welding, you don't need to constantly read the pressure.

Thanks @Darkblade, I was wrong on two things I said; The Acetylene is the vertical tap and that is the regulator that is sitting at 90į.
That regulator you posted looks great and the angle of inclination of the gauge is fine.
I must be making a mountain out of a molehill again.
Sorry to be a nuisance early on.

Nice thread. Is it okay to save or follow your thread? I am new in this hobby and planning to do a planted tank. But, i need to enhance my idea before setting up and I need this kind of help, well detailed information, from experience person. Btw, I signed up because I read your forum. 😬

Yes, of course it's fine to save this thread!

Alternative Regulators

Well, this is quite the informative thread! Thanks to all that have contributed so far. I was wondering if a flowmeter-style regulator would work for this operation and possibly get rid of the bubble counter? Here is a link to a short article comparing three different styles:

Thoughts?

Flowmeters can work, but generally only on larger aquariums. This is because for larger aquariums, the volume of CO2 that must be injected is quite large, making a traditional bubble counter (and counting bubbles), a bit meaningless, since you will be injecting gas so fast anyway.

Well you would have a problem with that one.

It's measuring SCFH, or standard cubic feet per hour. 1 SCFH = 472 cc/min. Most of us are injecting somewhere between 20 and 80 cc/min into a planted tank.

That is why the Dwyer flow meters are useful to us. In relative terms, we are measuring a VERY small amount of flow. Most meters simply can't measure our small amounts.

So what would be a ballpark rate for a 75 gallon tank? My plans are to plant a carpet (Monte carlo) and anubias, maybe some swords. At the moment I don't have my local water quality scores sitting in front of me, but there's got to be a relationship between rate of CO2 injection and volume of water. I'm trying to figure out what an appropriately sized system would be so I don't have to re-purchase different parts down the road. Again, the information on this site is very much appreciated.


Thanks!

Best guess is Dwyer RMA 151-ssv 5-50 cc/min scale.

There are lots of folks here who post their flow meter levels. Here's a thread that should help.

Thanks, that's what I was looking for. I just found this site a couple of days ago and haven't had a good chance to dig through it yet, but it seems to be chocked full of useful information. I appreciate your help :-)
