CO2 reactor....

Reactor's work for all applications, DIY Co2 into a reactor would actually be a good idea, since it would preserve as much gas as possible.

But Thrak, DIY through a glass diffusor does not always work, usually there is not enough pressure.

Well, i won't try one of those then! :D
Any money saved is good. I have tried the diffusion through the airstone thing, but i would only get one large bubble through it, and it seemed to always bypass the filter intake. Perhaps i can try a different placement. Maybe securing the airstone directly to the intake screen with a rubber band....
 
Your canister is your reactor. And you don't need nuthing but that L-bow.
No stones no nuthins.
Exactly.Since you bought a cannister filter,run the tube from the CO2 right into the intake for the filter,that's it.The filter will then mix up the CO2 and put it back into your tank.No need for a glass diffuser,which probably won't work,or a reactor.
 
It will all start to make more sense when your tank is up and running.
 
I made a reactor out of an old gravel vaccum and a power head that I had. I went to my local hardware store, go to the plumbing dept, find an elbow and a screw on fitting with a barb that will fit the the outflow of the power head and the hose of the gravel vacc. I went into the lawn irragation area. I pushed the elbow onto the outflow of the power head and screwed on the other fitting onto the elbow, then attach a small piece of the gravel vacc hose to the fitting with the barb, then to the top of the gravel vac, I melted a small hole in the side of the gravel vac and made it just big enough so a small piece of hard tubing would fit, adjusting it so that it would release bubbles under the water stream, then attached the co2 line to it. Add piece of sponge filter to the bottom of the gravel vac so the co2 will bounce around in the gravel vac, and get disperesed with the water. It works for me, it increased my concertration of co2 in my 30 gallon.
