Here's some feedback for you all. Not very positive.
1. Noise. It's interesting to hear the noise but I am sure in a week time I'll be deeply annoyed by this;
2. Less efficient combo. In my case the efficiency has decreased and I see plenty of tiny bubbles leaving the reactor. PH drop is slower. My flow rate is somewhere ~800 L/hr which is not that much, so people not seing any bubble whatsoever probably have a much lower flow rate in the reactor (either canister is slower or bypass in place). I don't think I want to sacrifice my flow rate with this reactor for better dissolution. I would either need to put that reactor on a separate loop with its own pump or switch back to my DIY reactor (which is probably what is going to happen). Another reason for these tiny bubbles being created is my venturi. I used a rather small tube size which is probably breaking CO2 a lot.
Some pics for the posterity. Don't mind the home made deflector and teflon. You got to do with what you have!
