I got a pinkish tint once or twice. I use distilled water doctored up with Bru’n water.

Interacting with vessel metals maybe? I wonder how many people are passivating their vessels.
I heat my water in an AL kettle. I do nothing to passivate it, but it does have a thick oxide layer. Not to mention that I use it every time.
I'm stumped then!
It's the BTB precipitating out something. Typically you'd think of iron or traced metals because common sense and the literature points to that. Since you said you see it before grains added, you can rule out grain contribution. The only thing left would be reacting with the vessel.
Not sure man. I've never experienced the purple so I can't add anything other than saying for people who experience it to compare and contrast and see where there is overlap.
