v285039 and all previous versions.
As i said Bottled Polluted water emmits Pollyted oxygen. So you could think what's the problem...
The problem here is not only in the logic of course. I personally do not understand how the duplicates fill plastic bottles, although plastic is not yet open.=)
So. You could build a 3 algae terrariums at the bottom of your base almost at the start of the game. Quickly did research of O2 Deodorizer and you would have almost endless oxygen generation while you have a water and sand for any number of dupes. Cause every bottle would emit PO2 that Deodorizer would change to O2 with 90% efficiency.
AT gives us already 40g/s|44g/s of O2 + 10g/s PO2 from every 349 PW Bottle. Not much right? No! It gives 1400% efficiency.
As you could see on shot i have 4 terrariums for the 5 dupes and all my base in 2.5k O2 where it needed.And yes i even didn't used algae distiller ever.
To be honest. I could remove 3 of them and my base still would be at current pressure cause i already had around 5-7kk of PW in bottles near deodorizers that would emit PO2 and change it to O2. Even if all the oxygen is pumped out of the base. Accumulated bottled water is enough to return the pressure to normal within half a cycle.
My record of this system is 410 cycles, 9 dupes with 1 AT and full asteroid clearance without any O2 automation. Could be more than 410 but i was tired to continue. And you could build it in 5 cycles from start of the game.
Also you could store endless volume of PW in a bottles at 1 tile if your terraium is under clear water
Steps to Reproduce
Build a deodorizer near algae terrarium or above it. And not to empty the bottles of dirty water
