NOTE: I specifically meant recirculating CO2 scrubbers. Not CO2 scrubbers in general.
TL DR. I'd like to run a "recirculating" CO2 scrubber on my skimmer but have heard, what are probably anecdotal, reports that it could drop your dissolved oxygen to dangerous levels.
Long text but I'm trying to give as much detail up front.
I want to bring my over all pH up. Pulling air from outside is absolutely not an option and I already run my lights for my macro algae on reverse cycle to my display.
I'm running an open top 80 gal 32"x24W" with a drilled over flow. It's using a Herbie style overflow so pulling siphon.
The drain ends underwater in my sump. The water in the drain camber then comes up and runs through 2 filter socks then the water goes into chamber 2 consisting of a Essence 130 skimmer and Skimz MBR 157 macro algae reactor.
Then into the return chamber. Flow in the tank is from the Varios S6 return that run to two 0.5" lock line returns terminating in RFGs and two gyre xF350 mounted vertical about 8" below the water surface.
The tank is an SCA 80 and sump is a older Red Sea Reefer 250 sump.
My pH generally runs between high 7.7 and 7.9*. Alk averages mid 6s.
In theory do I have an overall high enough gas exchange elsewhere besides the skimmer to not worry about tanking my dissolved oxygen by mostly "sealing" my skimmer cup lid and drawing the air intake for the CO2 scrubber from inside the skimmer lid?
*The pH probe is a BRS double junction probe that's nearly brand new and was calibrated before being put into service.
