Yeah I have thought about doing this in the past. My better half is not too keen on me drilling through our walls (or floors) to run a tube outside. She will be ok with a tube temporarily going to the window during the party I think, but I don't think she would be pleased if I told her it was permanent...

I drilled a hole through the side of the house (brick) and installed a 1/2 inch airline to the scrubber. It took the wife almost 6 months to notice it.
. At that point she couldn't really complain...been there that long she never noticed . Sometimes easier to ask forgiveness than permission I drilled a hole through the side of the house (brick) and installed a 1/2 inch airline to the scrubber. It took the wife almost 6 months to notice it.
Man I was really thinking about forgiveness than permission but thought that might be to far lol.
I just purchased some CO2 absorbent and hooked it up to my skimmer intake. My PH held steady at 8.14 through the night it's usually down to 7.7/7.8 and today it hit a max of 8.3 highest I've ever had. I had the same issue when I had a ton of people in the house it dropped to 7.6, haven't tried a ton of people over yet, but I can tell it's making a huge difference.
Try to name the physics law of gasses that says one can't exclude co2 by piping in o2 or any other gas
I think it's Henry's partial gas pressure law ok time to Google but how would that change the method here?
If correct I think it means direct adsorbtion via media is the way to go

Had this problem the easiest solution is to run the simmer air intake through some lye.. You can get that cheap on ebay and a coke bottle and rig one up in a few minutes with immediate results. Easier for me than running a tube all the way across the house.

Yet it is not O2 that impacts pH, only CO2. To drive out CO2 you'd likely drive O2 too high using pure O2.
Randy can you clarify again the pgp interactions at play
when someone is having enough people over to emit that much captured co2 I cant figure out how anything shy of venting the room, not the tank, or direct chemical adsorbtion against a gradient could work

FWIW, if the pH was really dropping to 7.2, then the CO2 level in the tank (and likely in your home air) is 10x normal. That's more than enough to cause issues in people.

For the last 8 years I have hosted the Christmas party for my wife's school. Figure about 100+ drunk teachers in my house. Never had a negative effect on my tank. In fact I never even thought about what effect if has on my tanks pH. I don't have a controller and only test my pH about every month. I only regularly test Alk (3 or 4 times a week). I dose kalk water so my pH, and Ca tend to stay in line.
Your change in pH would not bother me at all as long as it bounced back like it did. Having the toys that allow you to track your pH down to the minute are cool, but what you want to look at is long term stability (mostly alk). I feel that new tank owners tend to chase #'s and having the ability to track your pH that closely only tends to make it worse.

the partial gas pressure physics
I remember reading about it in other threads on your forum it was pretty tricky to recall for me. I couldn't envision how bubbling anything into the low-pH tank in a room with that many people could ever lower the co2 for the tank in question since the surface boil is just exchanging for higher pressure c02, more than what the tank itself generates. we had to clear out the CO2 from the room to help the tank, not apply a change to the tank...
when a tank itself was generating high co2 due to bioloading/organic decay if applicable then surface boiling the water via air input helped since it was gassing out into a lower pressure co2 environment.
I was recalling that pumping in medical O2 or atmospheric air would have the same effects on co2 since merely the turnover at the surface from upwelling/surface boil from an airstone was the action either bringing in co2 or expelling it based on the partial pressures of the surrounding room

I totally agree with this. I think I get way to worried sometimes about where my pH is at because it is always there for me to check.
