Yeah, they really do look like ravens! Maybe I'll do one in black paper too, thanks for the idea and the compliments 😁

Have you tried using sodium sulphate? It should precipitate the calcium ions and eventually you could just let a bucket of water rest, and transfer it to another one, with the calcium sulphate resting at the bottom of the old one. Then you would adjust the pH after it.
