Filtered, rain or distilled water. This family reacts to chlorine, chloramine and fluoride with crisp brown edges, even in a humid room. You do not need pure water; you need water without those three, and filtered and remineralized water does that from the tap.
What calatheas react to
Chlorine and chloramine, which stress their fine roots.
Fluoride, left at the leaf edge.
Softener salt, which is worse than hard water.
Cold water. Use room temperature.

Which water to use
| Water | What it does for this plant | Catch |
|---|---|---|
| Tap water | Carries chlorine, chloramine and fluoride straight to the roots | The usual cause of crispy edges |
| Tap water left out overnight | Loses chlorine only | Chloramine and fluoride remain |
| Distilled water | Clean, nothing harmful | No minerals at all; you carry and store jugs |
| Rain water | Excellent | Only when you have it |
| Filtered and remineralized | Removes chlorine, chloramine and fluoride and keeps minerals | Needs a filter |
