I came across this series on water treatment by a YouTube channel that I had not heard of before. I've so far only watched the first episode on boiling, but he seems quite thorough in his experimentation, research and explanation. I'm looking forward to watching the rest of the series and thought some others may enjoy it and find it useful, too.
I'd not heard of a 'WAPI' before!
