Stock and availability depend on your run.

Prepare an overnight treatment#

  1. Insert the liquid container and a power source.
  2. Check the current power demand and available energy.
  3. Let a night pass, then measure the container again.

Check a stalled batch#

  • Empty or missing container: no treatment.
  • Insufficient power: no treatment.
  • Reached target or no removable amount: no further improvement.
  • Quality and Performance solve different limits; more speed does not necessarily raise the ceiling.
