Cerges Reactor to Fluval 406

Hello,
I would like to "try" to make myself a Cerges Co2 Reactor and have it run with my Fluval 406. 17mm 1/4 inch ribbed hose.
I have been reading through all the posts on the builds and am not really sure which build has got all of the "kinks" worked out. There seem to be so many "tweeks" to this reactor I cannot make heads or tails of what is the best way to build it.
It would be very helpful to me if someone can direct me to the "last, best, tested"
build for the Cerges.
I have even looked for video tutorials on how to build one and connecting it...no luck :/ (someone should post one..hint hint).
So, if you have built one and are having success with it, if you would not mind posting photos along with detailed instructions, I would appreciate it VERY much!
Thanks!

I'm not familiar with cerges reactors, I made a rex grigg reactor and it works great, I just figured out the concept and designed my own. That is probably possible with cerges, find a build, figure out the concept,and design your own.

I had a hard time myself roaming around home depot looking for pieces to make the reactor for my fluval 406. The fluval piping is just such weird dimensions.

Hi WickedOdie,
Yea, the 406 does have the 17mm (1/4 inch tubes).
I know the Griggs is the same concept, but I really like the looks of the Cerges because you can make it see through and it seems to be able to be taken apart easily to be cleaned, if needed.
Hopefully, someone will post a "final" set of step-by-step instructions for me to go by.
I was hoping to gather the pieces today and build tomorrow, but no one posted
Thank you for your post!
Have a great night

Here is what I'm going to build



Obviously there will be a piece of pipe in there to make it longer. But the fluval 406 seems to be 5/8 inner diameter which sucks. So this is what I'm going to build, i'm going to try it without putting apoxy on the threads so that you can open the top and or the bottom to clean it out.

That looks like a good design. I hope it works without the epoxy.
Keep me updated.

I use a reactor like this, but my water still looks like 7-up. It just changed from CO2 to O2 from all the plants.

Well, I haven't built mine yet, but here's some links that I found when I was toying with the idea. And also, I think I've read that you'd probably want to swap out to real tubing instead of that ribbed stuff for easier connectivity.

There was a pretty definitive cerges thread here.. but the pics are shot.

It's still useful for all the ideas, like post 621 for a bypass.

Some more threads within the thread for ideas
https://www.plantedtank.net/forums/20...eactor-40.html
https://www.plantedtank.net/forums/20...eactor-35.html

Some part links (these may have been for a fluval 206, so adjust sizes accordingly, I provided them just to help you with sources)

So ua hua did a nice one with pics.

Hi ipkiss,
Thank you for the reply and all of the hard work you put into all the links.
As I stated in my original post, I have looked through all posts...even the videos.
No one seems to have given a "final" on their working Cerges projects (that I can tell).
In alot of posts, there were "tweeks" here and there, but no definitive answer to:
Does your Cerges Reactor work properly?
What was the final parts list?
How did they put it together?
What size reactor for x size tank? (Does it matter)
These are my questions.
I wish someone would share their knowledge and experience.
The final project would make a great "sticky" too
I have alot of patience, so I will keep bumping in hopes of finding some help.
Thanks all for the help so far

Yea, I don't think I've come across a definitive howto either. And you may not ever. It's like the CO2 regulator thread. There's just so many ways to go about the little modifications that people come up with constantly. That's probably why that first thread had 57 pages. Which is why some of the following links are the pages where I found sort of someone's build as I somewhat perused those 57 pages, and I personally came up with my "definitive" way of how I'd build it based on an amalgamation of ideas and sort of drew it out with the parts and their sources. Maybe an alternate method would be to do a google image search for cerges reactor and just get pictures of everyone's reactors to get more ideas to incorporate. I sort of had your problem until I saw enough of them to realize, ok, this is how I'd tackle it.

I think the basic idea is still mainly just running CO2 and water into the water filter housing on reverse flow. Perhaps the alleged original thread from Russia according to that first thread may be "definitive" enough for you http://translate.google.com/translat...n&hl=&ie=UTF-8
Here's the normal link if you want your browser to translate it for you. For some reason, google translate wasn't working for me in the first link.
http://www.aquaplants.ru/2007/08/06/...aktor_so2.html Other mods are up to you to decide whether its worth it or not to you. When I left my project lingering, I had decided that I wanted the cerges dwell time reactor setup that was described in the video because I felt that it'd be more leakproof to send the air in via a nipple on the in pipe instead of using the pressure relief valve on the actual water filter housing. I thought about using the bypass setup in that link I mentioned earlier, but I doubt my filter has that kind of flow that will overwhelm the reactor.

Anyway, good luck on the hunt!
