use in conjunction with canister filter. barb fittings top and bottom. large pvc pipe. smaller pipe for inside the larger pipe. 2 45 degree street that will move the pipe to the far side of the larger pipe. then proceed down with street 90's. drill small holes in the bottoms of every flat part of the 90's. do not the connect the last 90. co2 hoses one comes in the intake. the other recirculates the undissolved co2 back threw the cycle. questions comments concerns???????

this will significantly reduce the flow of any canister filter.
You'd be suprised what a few elbows inline do.

I have an fX5 that is hardlined on my 125. I originally used 90's. I replaced them all with 2 45's and a short pipe. flow was dramaticly improved.

Most C02 generators like this have nothing inside them, and are suposed to work well, I use a powerhead type difuser.

Also, often times people will simply place the C02 tubing in the inlet to the canister filter. this is also said to do a good job.

Ideally what you want to do is create some turbulence within an enclosure that will increase the duration of the C02 bubbles contact with the water. I might consider doing something similar, maybe a straight spraybar inside the encluosure, without the elbows.
Or better yet, use a couple street 45's to spray the water in the interior of the enclosure to start a cyclonic motion inside, then feed the C02 into the top center of the vortex, where it will be drawn into the water and moved into the bottom and out to the tank.

Hmm
I usually dont give up my good ideas.
I must not be feeling well or somethign.

anyway, keep us posted on what you decide to do.

will check out the flow rate with a 5 gallon bucket with ans without the 90's thanks for the info. will post the gph when i buy the 90's and 45's
 
I don't understand the purpose of the piping with all the 90's in the center of the tube. Can you explain? I'm in the process of building one like I linked, and I'm curious as to your thinking.
 
There's not really any point to your design. All it will do is reduce flow by a very large degree. The design the jbradt linked to results in 100% diffusion if built correctly.

Your design will be a headache to build, and truly it will not provide any benefit.


Before I used an inline diffuser, it was easy for me to see how it would work and why it would result in 100% diffusion, but it's kind of what I do for a living. I can see where some people would have problems visualizing how/why it would work, but just know that it does.
 
i am going to be running this on a 125 gallon tank eventually heavily planted. i will get more plants as i fined great deals around. the reason i have the 90's inside the pipe with holes drilled in the bottom portion of the 90's is

1. to allow water flow to go threw the 90's without great gph loss.
2. the holes are also for if the line filled with co2 it would give it a place to escape and recirculate.
3. co2 floats(duh) the bends and turns would allow great mixing as the water flow pushes the co2 along the way.
4. the gap at the bottom allows any remaining not diffused co2 to float back to the top and either be recirculated or defuse on its way up.
