How to remove carbon dixode

[WillowWisp]

I saw that you can use things to remove all other gases but how can I remove carbon dixode

Algae Terrariums and Carbon Skimmers.

or now slicksters in the oil update

Slicker is king in oil update.

Carbon skimmers are the most plausible option. You can also pump co2 into a room with morbs or slicksters,
in the test build (preferably slicksters).

Remember that gases have different weights, you can use that. CO2 goes down because it's the heaviest. Build your base so that the air can flow. Put important sections (sleeping quarters, dining room) at the top, so Oxygen would stay there. Put some Algae Deoxydizer at the top, so it would push heavier gases down. Put another one somewhere near your Printing Pod, where you still want Oxygen - it will push other gases even more (up and down). At the bottom of your base make a section for Mushroom Farming - they require CO2. Dig plenty of space, so the gas would have some place to drop. Put CO2 Air Vent here, if you have one (Natural Gas Generator etc). Between Printing Pod and Mushroom Farms put Carbon Skimmer. It shouldn't be too close to the the Mushrooms, because it will suck all the necessary CO2. It will use electricity only when it does that.
Watch the CO2 moving with F1 overlay. You will quickly see that the CO2 near Carbon Skimmer is being exchanged by Oxygen from Algae Deoxydizer. It's way quicker to get rid of it that way than with Algae Terrariums (powered vs non-powered). If you see lots of red, then figure out how to make it flow to the bottom.

Gas weights:
- Hydrogen
- Helium
- Oxygen (+Polluted)
- Natural Gas
- Chlorine
- Carbon Dioxide (CO2)

It's incredibly useful, when planning gas pumps. So you will probably want to pump gases for electricity, so Hydrogen and Natural Gas is your choice. For Hydrogen put a pump at the top of the gas hole. It might get mixed up with Oxygen, so one Gas Filter will deal with it (you can create Electrolyzer farms). For Natural Gas you want your pump to be at the middle bottom of the gas hole, filtering out CO2 and Chlorine if it's there.
Save Energy! Put Gas Valves close to Generator intake and tweak it just enough so your batteries would charge (it needs tests and observations). Put Atmo Switch next to the pump and set it to "Above 200" (depending on how many Generators you are using), this will let gases fall down/go up before they will be pumped.

Another note about natural gas separation, the column is not strictly vertical. While moving down, gases prefer to go to the right. While rising, they prefer to go to the left. So you generally want to put things like your sleeping quarters and your HydroGen intake Pump up and to the left, while your CO2 Skimmer goes down and to the right.

Brilliant observation! They don't teach you that in Wiki :)
