You are also confusing oxygen pressure with oxygen percentage, which are separate required values(oxygen pressure between the races limits and oxygen percentage of 30% or lower).
You bring down the oxygen pressure by selecting oxygen from the dropdown on the Enviroment tab, enter the desired oxygen level in the max atmosphere box, in this case 0.3, and hit the "save atm" button. It will proceed to remove some of the oxygen each construction tick until it reaches/drops below the max atmosphere you specified. You obviously need to have terraforming facilities or ships with terraforming modules present at the colony before the gas levels will start changing however.
The reason many use terraforming platforms/ships instead of facilities can be seen if you look at their costs.
Terraforming Facility - 300 Duranium, 300 Boronide, 0.25 million workers +infrastructure for workers
Tarraforming Module - 250 Duranium, 250 Boronide +other ship components.
As ship size increases the other components take up a smaller percentage until they become fairly negligible. The workers and infrastructure for them however remains at a fixed percentage.
You also have to expend much more fuel moving facilities via freighters in the multiple trips required than in the single trip to move a terraforming ship/platform.
The primary advantage to terraforming facilities is that you don't have to wait for a shipyard to become large enough to build your ship/platform and it doesn't tie up a shipyard.
