Are CO2 scrubbers beneficial regardless of ambient CO2 levels?

Does a CO2 scrubber only benefit a tank operating in a high CO2 environment, or will it also raise pH if the surrounding air has average levels? What levels are considered normal and elevated? I have a CO2 monitor on order but not sure what to do with the information it's about to provide me lol!

I'm no expert, but I think you can tell just by looking at your pH. If you get values below 8 you probably have high co2 driving it down (assuming you have a trustworthy ph meter).

I experimented with a co2 scrubber and saw my ph raise by about 0.1 during the winter while the windows are shut.
My tank is 20 gallons located in the basement where I work all day. There are 5 people in my family and we have 2 dogs. My pH will get down to 7.7 or so over night according to my pinpoint ph monitor (calibrated monthly).
I only have a small skimmer (sucking in relatively small amount of air) - if you have a big skimmer you might have better results.

A proper scrubber attached to a proper skimmer for tank size will always raise pH.

Even if you don't think you're having that much ambient co2, it'll always increase it.

Assuming my PH meter is accurate I get up to 8.5, but I'll get as low as 8.0-8.1 without it.

My house is lightly stocked with humans and animals lol, but I still was wondering if scrubbing would bringing my pH up from 8.1-8.2 to 8.3-8.4 and thereby benefit my tank.
