Black tubing is my CO2 going in. The tubing is suction cupped to the glass right below the filter, so it just bubbles into the intake. Notice the bubbles on the outlet.

I have the reactor surrounded with soft sponge and it didnt help much, not sure what else to do...

Other than that, i like this reactor a lot, it fits perfectly in one of the back chambers of my biocube, also helps pull water up from the lower intake grills. I dont see any co2 bubbles reaching the surface so dissolving rate should be close to 100%, just the noise...the constant never ending click click click!

The glass diffusers are never an option for me, they always get dirty after a while, not to mention blowing bubbles all over the tank destroying its "waterless" crystal clear look, also not that efficient.

Other power reactors are either too big, or i cant find a good way to secure the co2 tube properly.

The best option of course is the inline co2 reactor that uses counter-current for guaranteed 100% co2 absorption, not to mention completely silent and does not take up tank real estate. But that's not an option for me since I have a biocube and doesnt have a canister filter.

Anyway long story short (i know too late!), still using the elite diy reactor as it is the best option for me, but the noise is really annoying.
I also have a 29-gallon Biocube and I'm thinking about trying Niko's reactor design. Currently, my tank is plagued with thousands of microbubbles that are ruining the clarity of the tank. Not sure if all of these are from the CO2 ceramic diffuser or a combination of the diffuser and plant pearling.

One question though. How exactly do you reduce the noise newguy is talking about? I understand an airstone is involved, but where does it go and does it negatively impact the reactor's performance?

What stops the CO2 from escaping through the Elite Mini vents once the foam is removed and placed on the end of the venturi?

the vents are INTAKE vents.... Co2 won't escape through those, water is flowing INTO those vents. (just to clarify, the foam is placed completely over the outlet... the venturi hole is not used/can be plugged.)

for making it more quiet, I THINK the idea is to put a small airstone/pre diffuser at the end of the co2 line... to make it so lots of smaller bubbles hit the impeller rather than one big bubble....
I can not speak from experience whether or not that works however... (the bubble noise doesn't bother me one bit, your mileage may vary )

Thanks for clarifying Big_Fish. I'm going to build it tonight and try the airstone option. I'll post my results later.

one other item, I KNOW it's in this thread somewhere... you'll probably want to leave the flow regulator where it is. instead cut out ONE vent and put the co2 tube through the now slightly larger vent hole... trying to squeeze the co2 tube through the small slot left by removing the flow regulator tends to squish the tube a bit much. Good Luck!! I'm VERY happy with mine.

Yep, that's exactly what I was going to do. The plastic housing hole will also help secure the airstone to the CO2 tubing. BTW, what's the purpose of the foam?
