Gas Pressure

[Ares_91]

Hello!!

Kinda new to the game little over 100hrs. I have learned a lot every mistake I make is a lesson for my next colony. Now with that said, I always seem to have the same problem near cycles 100+. I have had about 3 colonies over 100cycles and my latest one 200cycles, now my problem is that for some reason and I cannot understand why nor I can never catch it (even if I reload to prior cycles) Gas pressure becomes a problem. My vents stop giving out the oxygen being produced by my electrolyzers and suddenly my entire colony is filled with CO2. suffocating and killing about everything. 

I have tried having a room just to pumped CO2 for the Carbon Skimmer to do its job. I really don't run a lot of NG Gens. 3 max (due to the same reason, I can't seem to get past that Gas pressure wall to grow more. On my last playthrough, I even built about 2 more Carbon skimmers to get rid of most of the CO2 but it was too much/too late at that point. I tried going back 10 cycles and diff approach and still same results. (several times). Prior to this, I was running fine on algae, world seed was generous on algae this time. I had no issues with gas pressure. had automation set up to when gas pressure would hit below a certain point Algea deox. would start up and so on. I tried the same automation with Electrolyzers but it was futile.

If any of you have a better way to deal with my problem, I am all ears. 

Thank you all,

build more carbon skimmers at the bottom of your base and have them loop with a water sieve

Build a small-ish closed room with a carbon skimmer and a CO2 vent.  Build it where the room starts with only C02 gas inside and seal the room. One skimmer can handle the output from five NGGs provided it has adequate water flow (both in and out).

Will do that, thank you.

Hmm.   Not sure why CO2 buildup is such an issue for you.  For one thing, Dupes breathe out a lot less CO2  than the oxygen they breathe in.  So usually I find that keeping the pressure of my base high with new oxygen always seems to be a a harder job than eliminating the CO2.

Anyway what I do is pretty simple.

The Entire bottom level of my base is designed to be full of CO2.  That's where my storage, or mushroom farm, or whatever is, so I never worry about CO2 until the air pressure is over 1000 and CO2 starts appearing on the second floor.
I always put a vertical airlock at the center of my bottom floor and dig a 3 tile wide shaft down under my base until it connects to some big caverns (which tend to have very low air pressure to start out).

As my dupes move in and out of that door the CO2 will tend to fall out of my base down the shaft and into larger caverns below.  That usually makes it so that CO2 is never a problem.

BUT...  If pressure is above 1200 and CO2 starts appearing on my second floor I'll open the door for a minute or so and let the CO2 fall down the shaft, then close and lock the airlock again, problem solved.

As I play I keep making progress on that downward shaft digging out new  tiles (Creating a vacuum in their place) and connecting to more underground caverns (more space  for CO2 to go)

Then eventually I break through to the oil biome and the CO2 falls down to the slicksters who eat it and covert it into  Crude Oil, solving the problem permanently.  In 20 300+ cycle playthroughs I don't think I've ever used a CO2 skimmer to pull CO2 out of my base, only to process the CO2 waste of machines such as the coal power plant.

maybe that is actually my problem. I tend to go sideways and I do little going down. Thanks a lot!
