My C. cranwelli's housing is a 15 gallon glass tank with live indoor plants and coco peat as substrate. I have to mist the enclosure regularly for the frog and for the plants.
But it is impossible to avoid misting the glass.

The problem is when the moisture on the glass evaporates, it leaves white mineral deposits.

I was once told to use de-chlorinated water to prevent that so I did what's instructed
But the problem persists.

How can I remove the stains? Better yet, how to prevent it?

Thank you
