I get that. I have one as well. Quite a small house too.

Always Making Something
Hm. One thing I'm wondering (maybe @Randy Holmes-Farley can chime in). Why is it that running air from the outdoors into the skimmer had little to no effect on Mindi's pH, while using a CO2 scrubber had a very dramatic effect on pH? I think I've seen this in other threads as well, so I don't think this is unique to this tank. It just seems strange that fresh air from the outdoors seems to only offer marginal improvements in pH in some cases, but a CO2 scrubber offers a much larger improvement.
I'm assuming it has something to do with the volume of air the skimmer is using, and the fact that there is existing CO2 in the outdoor air to begin with (albeit much lower than what we have indoors). Perhaps the existing CO2 outdoors was enough to prevent the air ingested by the skimmer from significantly changing the pH. After the CO2 scrubber, ostensibly the air would have no CO2 in it at all. I suppose this could then mean that the same volume of air would affect pH much more significantly. It just seems odd that there's such a substantial difference.

There's co2 in outside air.
