i guess you guys don't like newcomers...

I don't think your conclusion above is sound...

If you're handy with PVC pipe, that would work fine. I'll let some others with more experience building this particular reactor themselves.

Meanwhile, I hope you don't think this is a beginner-unfriendly site, because my experience has been just the opposite.

It is advantageous to have a transparent cyclinder like a viewtainer, but it isn't essential. The transparent cylinder lets you see what's happening inside, and lets the reactor serve as a bubble counter too. But, viewtainers are not at all made of thick plastic, so you could use half of a plastic soft drink bottle, or some other clear plastic bottle. You just have to be willing to experiment.

All you do is look up Welcome to Viewtainer
You can order or ask them if there's one locally.
Canadian tire often carries such items or a similar one.
Buy several and sell them after you make a few.

Use Google if you are looking for something hard to find locally, you are web savy ?

That, and some in Canada might not have frequented this thread, rather than that we do not like newcomers, is much more the reason. Just repeat the question or PM me or someone in Canada etc (Ottawa Aquarium Society etc).

You'll get a lot more response that way.

Vaughn,

I have 4ft of 2" Clear PVC for a few photo projects and a few DIY's CO2 reactors. So if you or the club wants a 1ft section, let me know, they are about 10$ for 12" or so.

They fit precise PVC fittings, unlike acrylic and it's tougher.
If you want some acetate (same as the viewtainers) lengths, go to Florin road, Tap plastics right off HYW 99 have it. Several diameters and caps etc.

Dear All,

I have a long ~30lts tank. I found the methods described in this forum really work.

I have found an empty tube obtained from my branded vitamin c effervescent tablet product. I am sure the material is absolutely non poisionous.

Then I drilled three holes to connect the CO2 supply with an atomizer (I mean a $1.5 gas stone) inside the tube, connect the venturi loop, and plug to the powerhead like a silencer to a gun.

I am now getting misting with lower CO2 rate (bubbles / min). The tube is 10 cm long x 2 cm in diameter. It works very quite and no abrupt bubbling.

It is recommended for small tanks like mine.

Thank you for all your contributions.

I was reading the instructions on how to make a diy co2 reator using a powerhead, which I have. It says you need an OD Viewtainer. What is this?

One person used venturi loop. What is this?

See diagram, also, you do not need a viewtainer (see green top clear plastic tube), the above poster used a Vitamin C bottle for example, anything that's semi soft plastic and clear will work, but might not look that attractive...........

Really up to you.

Viewtainers are for sale on line, just go to veiwtainer.com

Viewtainers are sold as storage containers for workshop use - for screws, nuts, bolts, etc. The clear cylinder lets you see what is stored inside, and the slit cap lets you squeeze it to open the slit so one screw drops out. Once I got my brain engaged properly and understood this, finding them in Orchard Supply Hardware became very easy - I looked in their home workshop tool area. Before that I couldn't find them anywhere. Now I suspect they are sold in many stores, but just not featured in any way so they would be easy to find.

When you buy one on line the shipping cost is almost as much, if not more than the cost of the viewtainer, so finding them in a local store is a good idea.
