I believe what you described is exactly how this works. The water flows from the top to the bottom of the reactor. The Co2 is injected at the top of the reactor, and pushed downward by the flowing water. The CO2 is 100% diffused into the water as no bubbles make it out of the bottom of the reactor.

Wow! Using Sparky's reactor, I'm getting the same CO2 level in my tank with HALF the bubble rate that I had to use before!!

Anyone tried this w/ nylon pot scrubbers instead of bioballs (they're cheaper)?

Should work. The whole point of the bioballs is to provide a media to break up any bubbles of CO2 that get in, and to provide some turbulance to cause the bubbles to dissolve. With that in mind, I'd think pretty much anything would work.
In the DC Metro Area? Check out GWAPA and WAMAS

Looks awesome. Can you post a list of stuff you someone would need so we can make sure we get it all at the hardware store in one trip?
I'm selling in line co2 diffusers. If you're interested in buying one PM me.

Where did you get the Clear PVC? Places I checked sell it online in 10' sections (cut in half) and is expensive. Have not seen it local Home Depot -Lowes etc...
I also like the clear idea to see whats going on!
Thanks --

I will sit down and post a list for you later this evening.

You are exactly right, I purchased a 10' piece. I needed two of them for myself and had 3-4 other people that wanted them made as well so I decided to go into production.

Hey people

I think I'll have a dip at this.... Sounds like fun.

Re: the adhesive that you have used to stick on the PVC to the clear tube, I need some help.

I assume that you have used a plumbing type product. Obviously (??) it will be under pressure... so I imagine this needs to be taken into account. I went to the hardware store and found:

* green pvc pipe cement designed for pvc under pressure. as opposed to the blue stuff for "normal" use
* pink primer (not purple) used for under pressure situations (what is this?)

So I gather you're supposed to use the pink primer, then follow it up with the green cement.

but the primer has the ingredient Methyl Ethyl Ketone in it. I understand it to be toxic so I'm not prepared to risk using it on my tank.

So I'm stuck on what sort of glue/adhesive I can uise. I'm also a complete DIY n00b and have no idea about building materials and products, so sorry if I don't understand everything.

Can anyone offer a little help/advice? What brands/products can be used safely?

I doubt ill get a response as this thread is over a year old, just wodering what size of brass barb you used for the co2 inlet? I plan on doing the same thing but instead of all the couplings im just going to cap the pvc and drill holes to glue to thread tape the water inlet outlet barbs. and im not using pvc but abs. and as the thread above mentioned the abs cement does contain that toxic chemical.. but all the oatley cements sealents etc have that so im assuming its safe.

use whatever size you need to, to fit the tubing you have to deliver the co2.

If you put off what you can do today until tomorrow it will never get done cause tomorrow never comes. It's always today.
