The bioballs do two things:
1. increases turbulence
2. slows flow and increase pressure

Both can increase dissolution rate.

Questions:
What kind of canister filter are you using?
Theoretically I could use a hydor in-line heater on the output/other tube?
Great video, thanks!

You would have to mount a power head inside your tank to the reactor then back to the tank. Not the best looking out most elegant way to do it.

Why aren't you injecting the co2 @ the bottom of the reactor intead of at the top?

It seems like with the counterflow system you set up, moving the input to the bottom would result in longer dwell time.

Am I missing some logic?

Btw, nice job on the video & explanations

the water flows from the top where the barb is down then back up to the tank. with the barb in the top the bubbles are in the reactor for as long as possible.

Great Video Sean, very informative. I was thinking about something like that, but my sump and all equipment is down stairs in my fish room. I was thinking of the same type of set-up but with reactor attached to the outside of my sump then running it up through the bottom of the aquarium into a wooden air stone. I already have 3 air hoses in the tank I drilled when I first set it up, I could rig it up where I could change out the water in the tube with my water changes. Also where did you get the tube from? Thanks

Is it glued at both ends? How do you clean it?

Hey guys,

I was using this reactor on a Marineland C-360 originally, and it was working great, but now i upgraded to the Marineland C-530, the added flow gives me a less efficient reactor, the flow grabs ahold of the Co2 bubbles and they get taken up into the tank before they get a chance to fully diffuse, so im having to add more Co2, not to mention theres a lot of bubbles coming out of the return to the tank. The C530 doesnt have a way to restrict the flow, so i have to add turbulence and restriction in the reactor to bring the efficiency back up. I got a bunch of plastic pot scrubbers, i got three packs of 6, how many should i put in the reactor? Also, is there any down side to taking out some bio balls and replacing them with pot scrubbers? I dont mind if i loose some flow, infact thats a good thing, theres too much flow from that filter for my small scale 110.

thanks for any input!
