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.
