My DIY CO2 Reactor


Well I finally built my very first CO2 reactor after having used a diffuser for the last year or so. I have to say that I was impressed when I hooked it up and it actually worked. It would be wrong if I did not thank Tom Barr and Rex Grigg for all their great information that I found posted on numerous web sites. I basically just combined the elements I liked from each of their reactors and made my own version. This is what I did.

First I gathered all the parts including:

1- 2" reducing T with a 1/2" threaded side port
1- 2" Coupling slip
1- 2" Plug
1- 2" Reducer Bushing with a 1/2" threaded port
1- 12" Clear PVC pipe
2- 12" long 3/16" tubing
2- 1/2" hose barbs


This is what all the parts look like laid out waiting to be assembled:

The first thing I did was drill two 3/16" holes in the top of the reducer bushing like so:

Then I inserted a 12" long 3/16" tube in one hole for the CO2 line to attach to and a 3" long tube that I will later attach an extra piece of CO2 tubing to with a valve so that I can release any built up gas at the top of the reactor:

After assembling all the pieces, this is what the finished product looks like. In this picture you can see the extra piece of CO2 tubing I attached to the 3" interior tube. It has a drip irrigation valve attached to the top which I will use to release any back pressure that builds up. Luckily the reactor has worked pretty efficiently and most of the CO2 injected is being dissolved. I have not had to release any trapped gas as of yet. :

This is the reactor attached to my filter and CO2 System. Using clear PVC pipe allows you to use the 3/16" tube as a bubble counter so you know exactly how much CO2 is entering the reactor:

Well thats my reactor. Hope it helps anyone trying to build their own. Good Luck.

Yes it is. It fits regular PVC fittings and you can use regular cement and primer.

I bought mine from here:http://www.aquaticeco.com/subcategor...Clear-PVC-Pipe This company sells the clear PVC by the foot and its hard to find a place that will sell it buy the foot. Most companies want you to purchase numerous feet of the stuff. This is also a great company to buy aquarium related supplies in general.

Petco sells rigid tubing but I managed to score some more from a local fish store.

I like how the reactor is a hybrid between Tom Barr's and Rex Grigg's, it combines the best features of both. I was wondering where you purchased the reducing T. I couldn't find one so I had to resort to using a 2" T and another reducing bushing.

If you could attack some kind on diffuser on the end of the longer tube, you could probably get better diffusion
