DIY CO2 Reactor

Looking for ideas on a large diy co2 reactor for a 110g tank 60x18x24
have a Blue Line 55 HD 1100gph pump split into 2 leg.
1. Nu-Clear 533 an 547 filters
2. diy co2 reactor , Would a 3" or 4" x 15" or 24" size reactor with a 1" input/output be enough for a large tank with lots of flow? { Was think old fashion with bio balls}

What are your thoughts?

Yep should work just fine.

3" diameter should be sufficient, especially if you can adjust the flow a bit. With 4" the velocity within the tube goes down too much IMO. I think 15" is on the short side, additional length doesn't hurt as long as you can fit it underneath the tank. Around 20" would be my choice.

And I wouldn't use bioballs or anything in there at all. It just leads to gunk and clogging issues. These reactors work really great by creating a slow flow zone (starting to sound like Dr. Suess) where CO2 bubbles are kept in motion until they dissolve. No real need to "break them up" further.

Well....you could use a Rex style reactor or one that is fashioned from a RO filter housing. You don't really need anything elaborate with bio balls. Keep it simple. You might also consider a Mazzei injector for that high of flow.

jgmbosnia1, I'm running a Mazzei right now but can't seem to drop my PH or my DC color down to transparent blue color {7.2 ph} I'm running my BPS up high also an I don't like that idea.
My back up idea is ether a Atomic CO2 Diffuser 65mm from GLA or a DIY CO2 Reactor , I had made one before when I had a 55g tank and have a AM1000 co2 reactor in storage .
I made one similar to this one :

It came out real good , I did wanted to use one of these but I could only find them in 1-1/2 inch only:

I do, I do.



This could be 2.5", but you get the idea.

I would agree that if you have enough width/length so that that water is going at the right rate you shouldn't need any bioballs, etc.
