Despite my best efforts, I can't stop slimelung at all. You can see on right side, I have 3 deodorizers changing polluted oxygen into oxygen and a locked airlock door, but slimeslung is still passing through, and not only passing through, just growing and growing. It isn't dying off.

I had to break into because the seed I got had very little sustainable water

The food poisoning all over the place, including on your ration box, is a bigger threat than that tiny bit of slimelung at the edge of your base.

The slimelung germs will die off as the oxygen is purified. It can't live on pure o2, the germs just take some time to die. You can always speed the process up by spamming more deodorizers and if you can't scrub or refine the loose slime chunks on the ground, put them into a storage compator and walled it off - loose chunks like that will emit polluted oxygen with more slimelung germs on it but the tiles of slime you haven't dug out will not.

You could also build another algae oxydizer to help increase gas pressure within your base to keep the polluted gasses from coming through your airlock.

the food poisong has been none issue.

This is my point though, that slime lung ISN'T dying off. Its slowly growing as the slime biome to the right makes more germs than oxygen is destroying. That small amount of slimelung was non existant 10 cycles ago. Its growing and I can't stop it.

Only the slimelung germs in the air will die off, when you purify the air by deodorizers.
When slime remains somewhere it will always spread unto the immediate surroundings.
As black goat already said, if you want to speed the process up, just build a dozen of deodorizers...

Slimelung isn't that dangerous. It is always cureable. So, if someone gets sick, you'll loose his working power for some cycles, yes.
It is only dangerous, if there are many sick dupes, at the same time.

To stop the slime polluting your air you can build a locker under water and store the slime inside. The germs will remain on the slime, but it will stop polluting your air.

Slimelung absolutely does not grow on O2, read the database entry or the germs tab on the infected tiles if you don't believe me. You have to make more pure O2 and deodorize more polluted O2 in that slime biome to clear the germs away.

In the 6 minutes it took you to reply to my post you couldn't have tried my suggestions so I'm not sure why you even made this thread if you don't actually want advice.

I know what its supposed to do. Im explaing to you whats actually happening in game lol. It grows in polluted O2, it growing the slime biome quicker than its dying in the O2, so its slowing growing in the Oxygen because its growing quicker than its dying.

Of course I haven't tried yet, im not in the game at the moment. So the only way is to build 30 deoderizers. There isn't a correct way to preventing it from spreading?

[Strygald]

It's simple... your deodorizers are doing what they are supposed to do and converting the polluted oxygen to clean oxygen... which will cause the Slimelung to die off. BUT there is a pool of polluted water which will slowly convert into more polluted oxygen, so you need to pump out all that polluted water and run it through a water sieve. Once all of the polluted water is gone, the remaining polluted oxygen will be converted to clean oxygen and all of the slimelung will eventually die off, leaving the area clean.

If you ignore that polluted water you'll be fighting a losing battle in trying to get rid of the Slimelung.

[Tarshaid]

The deodorizers you've put will only purify the polluted O2 that's nearby; in the meantime, the rest of the polluted O2 will keep making slimelung multiply. The cavity is quite bigger than their area of effect, there's no reason for the pocket of polluted O2 at the far end to ever decide to come near your deodorizers, and the polluted water will keep spawning more polluted O2 until the pressure is too high. So you either purify all polluted water, or you produce enough O2 to stop any generation (or anything really, but I'm not sure you want to fill that pocket with natural gas): check the oxygen pressure in that pocket, I'm ready to bet it is low enough to let the polluted air grow.

Still, that area isn't the one where your dupes live, and that one area seems to have food poisoning running rampant. What the hell is an outhouse doing with no wash basin beside it, but a microbe musher instead?

As long as you have slime (dug or undug) touching the polluted oxygen you'll always have slimelung growth. And dug slime will always produce Polluted o2.

Polluted o2 just hangs where it is basically, it doesn't drop or raise in Oxygen so you have to put the deoderizers near the P02 to kill it.

You could put in some temp rows wiht Deoderizers dig out the rest of the slime and store it in a container in chlorine (add some deoderizers above it to convert the Po2, or put it in a container under water.

Beyond that, it's not a fight you're going to win. ;)

No.

Polluted oxygen is just a slight bit lighter than pure oxygen. So, in time, polluted oxygen will float upwards and settle on top of pure oxygen, eventually.

If you want to stop (dug out) slime from polluting the air, you'll simply have to store it inside lockers beneath water.

You don't need a tonne of deodorizers, just a few in tactical positions to clear out any and all polluted oxygen.

20 in a line will do less work than 4 in spots where there's actual polluted oxygen.

Block off or clear the polluted water. Store the slime safely (either underwater or 1.8k gas pressure). And let time and clean oxygen do the work.

I feel your pain. I had a pocket of PO2 that got trapped under an overhang in my base and the slimelung germs migrated through a dozen tiles of O2 and seemed to get stronger every cycle. I don't remember them spreading that aggressively in the past. The others are right, though; the only solution is to go after the PO2 aggresively. Stop the source and it will eventually die off.
You can also slow the spread by controlling temp. Slimelung likes warmth, so keeping your base cool will slow the growth. I accidently killed off all the free slimelung in a swamp biome with my ice-mining operation. I had a conveyor shipping ice, ice sculptures, etc. Before I knew it the slimelung was gone. I was just trying to fill my new resevoir with cool water.

Well that was my goal. I dug here to get to the PO2, so I could utilize it. But I feel like the slimelung would get way out of hand before I even got started.

Hmm, perhaps you're correct, but in regards to what he's doing I'm not wrong. Eventually isn't useful and my method as describe works very well to remove Po2.

I'm over cycle 600 and my ENTIRE Asteroid is full of air and the Po2 is still where it was before. Perhaps it floated up to rub against the tile above it, but it makes no effort to go around the tiles to float. Which still leaves you putting deoderizers all over the place to remove it.

But technically speaking, I guess you're not entirely wrong. ;)

No offence taken, pal.
Here is a fine little tutorial about gases, where you can see the different weights of gases at around 1:40. Enjoy!

yeah, but that change is a snails pace now. I used to count on the gasses separating a ways back, not sure when they made the major change in gas movement. But it's dramatically slower than it used to be.

Even the gas pump at the bottom of a map with 1700g+ of oxygen doesn't move the nat gas and co2 to the bottom right like it used to.

On my map I have a pump down and to the right of an oil refinery and the nat gas is still far to the left even though the o2 in that area is around 1500g.

At least it's not like real life where it's all mixed together and you can't tell at all. ;)

If you're going to open up slime like that flood the area with a Chlorine pocket, wait 5 seconds and then do what you want. Instantly kills the slimelung so if you want to leave the Pwater to gas for O2 it won't kill you. Dupes holding their breath also keeps the Slimelung out...

From the pic, man I'd never go in there like that, it's just an excuse to make a mess and get your dupes sick.

Rule No 1 in ONI..: Don't make problems for yourself. That's a clear case of going in unprepared to deal with consequences and not having a back up plan in case it all went wrong.

Short term, pull a Buzz Lightyear: Deoderizers....Deoderizers everywhere... Go over kill, they're incredibly cheap for what they do. Work from where you live outward, one every couple of tiles at varying heights. (just look at where pockets are forming and stick one in it)

Option 2: Flood the area with Chlorine or set up a bin in the pit and place Bleachstone in it.

Put up a floor and door by the battery and limit the number of dupes in that area to cut down early infections to one or two dupes. Rotate them if you can so no one dupe takes all the Slimelung.

Regardless of solution once everything is under control:

If you want the slime to gas, place a couple bins far left to make cheap O2. Deoderize it well at various heights to clean up the O2 as much as possible. (still limit interaction and rotate dupes so they don't get infected and just pop deoderizers in wherever PO2 pockets form)

If you don't want the slime to gas, make a narrow cistern with a ladder along the near (to the base) wall. Fill it with the Pwater and place bins at the bottom. You want it on the narrow and deeper side of the things to cut down the surface area to slow gassing. Store the slime under water, it won't gas. 2 or 3 deoderizers over the pool will take care of any Pwater gassing. (you can also make bin size cisterns and fill them with Pwater, just have a tile in betwee, dupes will jump over. or make them 3 tiles deep and have a ladder over top of the bin)

For the record, you have food poisoning germs on your water pump and you're using the musher. Looks it won't be long to where you won't need slimelung's help getting people sick, if they already aren't making Pwater of their own. If you are going to mush, you have to keep germs out of the water. Why I never use the musher. ever.

Cheers..!

Don't forget to set your deoderizers to a higher priority so that the dupes actually fill them with sand. I like to put storage in those areas (other side of the airlock) and set them to only store bleach stone again with higher priority like 7 or so. You might also want to use more than one airlock door. I use 4, 2 upright with 2 sideways in the middle.

Also IDK what these people are talking about with food poisoning. Maybe i've been lucky but it seems like food poisoning only makes them go to the bathroom and have diahrrea. I cant remember a dupe ever even using a med bed from food poisoning let alone dying.
