Stupid question..what is a recirculating scrubber?
Instead of pulling in air from your room to run through the scrubber, you run the input line into a hole in the top of your skimmer. So you're scrubbing air that's already been scrubbed and injected through the skimmer. Less CO2 to scrub, makes the media last longer and raises pH better.

I strongly recommend you add a moisture trap. They didn't have one on that setup. I didn't either when I first started mine, and had a ton of water in my scrubber chamber.Building a DIY recirculating CO2 scrubber with your skimmer - #AskBRStv Live

Going to take my mositer trap off my bubble magus and repurpose it. Thanks for the heads up
You could probably run it through a mason jar and be fine.

Randy - do you have a handy way to determine if oxygenation is an issue in our tank? Other than the fish gasping, of course. Would be easy enough to drop an airstone into the sump if it became an issue.Just keep in mind that if you recirculate skimmer air, you remove one of its potential benefits: oxygenation.
But wouldnt the airstone itself defeat the purpose of the C02 srubber in the first place?
Potentially true. Before I had the scrubber set up I used to have the air pump setting on a protected window ledge outside I only had to leave the window open enough for tubing and cord. It helped boost my ph a bit. I quit using it when I set up the scrubber though.
This comment confuses me. Assuming the media (kalk) strips out the co2 through absorbtion and that the oxygen is absorbed into the water, eventually wouldn’t this create a slight vacuum in the skimmer and thus pull in outside air though the loosely fitting skimmer cap? Struggling to see how this would prevent oxygenization if air is being absorbed though the media and the water. Since the bubbles continue means it’s not running out of air. What am I missing?Just keep in mind that if you recirculate skimmer air, you remove one of its potential benefits: oxygenation.
I was wondering the same thing, but was not even sure how to ask it.... Seems to me if the PH is staying up then the CO2 is staying low but chemistry was never something I was good at.
