Air extractor to lower Co2

[moiy24]

Hey guys

I just bought an air extractor, I plan on installing it on the wall behind my tank since it sits behind a wall to the exterior and I have a high level of co2 in my house

I've tried the scrubber, kalk and skimmer outside line.
My question is if I should install it outside so it blows fresh air in or inside so it blows the co2 out?

Thanks

My ph lowers to 7.65 without the scrubber.. with it it goes to 7.8

I would blow fresh air in. Pulling stale air from your home will be a never ending task..
