I'm running a CO2 scrubber on my skimmer to keep my pH above 8. Using that in combination with kalkwasser, I've been able to keep my pH in the 8.15-8.3 range. Anyways, since the CO2 scrubber media can be a tad bit expensive as a re-occuring cost, has anyone here tried the re-circulating method? What safety stops do you have in place in the event your skimmer overflows? Any worry about lack of gas exchange with FRESH air using this method?
