I was just looking around and I was wondering if something like this could get me going? The big thing that I wonder about is the psi.

Right now I am just kind of looking around but I a thinking that doing a real Co2 tank would be nice and easy compared to having 3 DIY bottles of brew going.

Are the CO2 units for larger tanks that expensive? I would think buying welding equipment would cost more than a basic CO2 kit. Although the only thing I have looked at is the Hagen ladder kit for smaller tanks like my 25g. It is $40 Cdn. at most retail stores, it would be a lot less in US$ wouldn't it. And I have to admit that I prefer to spend a bit more and get the 'proper' set-up rather than save a bit then mess up and have to shell out more. Basically I have no answers for you, I'll just go away now.

Hi,
That system is fine for supplying your restaurant with
CO2 for sodas, but not one I'd use for aquariums. In
aquatics we measure the flow of CO2 in bubbles per second.
The flow meter is not something that we would use. You
would be paying for something useless.

The tank you show (5 or 10 pounds) would be perfect.
(I use a 10 pound bottle)

This is a typical regulator assembly that we would use:

This is what a typical bubble counter looks like:

This is a sample of a diffuser:

This is a sample of a reactor:

The gas is injected or distributed in the tank with either
a diffuser or a reactor.

Use only CO2 "safe" tubing, regular air hose for aquariums
are porus, leak, and the material reacts with the gas so
the line becomes brittle.

So there is no way to tone such a regualator down? How does the bubble counter work? Pretty much everything else makes sence to me. Thanks!

P.S.

Frank,

What did you think of the article?

Wings,

A bubble counter does nothing else then what its name offers, it counts bubbles .

This is more or less important so you can see the flow rate to the tank as I would assume you don't need more than 2bps (bubbles per second) for the 40G (that;s the tank, right?). Adjustment to the bps is done via the needle valve that is in the regulator (not the main handle).

Hope this helps,

Ingo

I musta been half asleep and no coffee... What article?

Frank,

Tom Barr's article....

LF,

Thanks! Why can't you just run the hose under the water and count the bubles then set it up?

Wings,

That is a great idea, except:

- Needle valves tend to be a little tricky and require adjustments until the flow is just right. In my case that took weeks
- When the canister volume decreases then there is less pressure on the needle valve to push it open and it might need adjustments
- In general you want to make sure your flow rate is what you want it to be, like when you decide to up it a little for better growth etc.

In general, a bubble counter is not required for a CO2 setup, but some form of it (some people use a ladder diffuser and count the bubbles in there) is sure helpful.

Hi,
OH, THAT article... I thought it was an
interesting article, so much so that I've decided to
try it as an experiment.

Wings,

Glad I could help

Frank,

It works for me, Bensaf, tetratech, and NowherMan6 - It can't be wrong
Just keep in mind that you have to do it not for just a few days.
