Making clean water using 3 simply steps

Thank you for your feedback! My previous guide was only suitable for the early access. Since the game changed so much after the launch, here is a new guide for cleaning gems out of your water!

Empty a room of any gas - fill it with Chlorine
build 3 - 5 liquid reservoir
The room would be more effective if it was with a water lock instead of an airlock
Fill up the liquid reservoirs, wait for a cycle - the water in the reservoirs will be gem-free

* The biggest problem that we are all facing after this new update, how do I get clean water?!
Don't worry my friend, the ultimate guide is here, just follow these simple steps, you will get your clean water in no time!

Step 1: Build Liquid Tepldizer (under utilities, the 5th machine ) in your polluted water source.

Step 2: Build Thermo Regulator (under utilities, the 3nd machine) where the heated water comes out

Step 3: Build Water Purifier (under Refinement, the 2rd machine) where the cooled water comes out

** Remember to build your polluted water tank with Insulated Tiles**

If you want to make sure your water is clean before it goes back to your clean water tank, build a second polluted water tank (repeat all 3 steps)and purifier your water one more time.

Any suggestions please leave a comment.

Thank you!!!
