Change Log:

V1.9

Made it available sooner in the tech tree.
Increase cleanse rate to 15%.
V1.6
Added some AI priority coding for the base cleanser in order to help the AI use it to lower its polution.

V1.4
Backtrack last change to improve v 2.2 compatibility. Once upgraded, you can no longer build the base version on the same planet. You still get a free orbital slot when building the T2. The T2 is still undestructible but be careful because you can still replace it with another orbital. If you do you will no longer be able to place any atmospheric cleanser down again on this planet.
V1.3
In order to fix the issue of not being able rebuild the T1 after destroying the T2, the bebhaviour of the mod was change: now when you build the T2, the planets get a free orbital slot and then rebuild the T1 for free. The T2 is indestructible to prevent infinite slots exploit. The T1 can be destroyed at will. Total pollution reduction remains 15% with the added bonus of 0.1% per turn reduction.

Once upgraded, you can no longer build the base version on the same planet
