Getting PH up with out buffer?

[acr0p0ra]

With the windows locked up and the AC on full time, Im getting a lower PH then I normally would.

I have heard of people drawing air from the outside via skimmer. How does this work? Can I just run a longer air hose from my skimmer out the window so its sucking fresh air? Will this affect my skimmers performance?

What other ways are you guys maintaining your PH?

Yeah on the skimmer air intake.. Other ways is a c02 scrubber or top off with kalk..

acrOpOra Trolee has it on the air intake of a skimmer and the co2 scrubber and kalk. As kalk was use as a co2 scrubber for the first submarines.
What are your numbers of Alk or DKH? And pH?
