First, I admit that I know nothing about city water treatment systems and am no chemistry expert, but this article on MPR,
https://www.mprnews.org/story/2017/1...ater-pollution, about how road salt is bad for water made me wonder if our creation of saltwater for home aquariums contributes to the problem.
One line in the article says: "Once salt is in a body of water, it's nearly impossible to remove."
My city's water treatment web site says: "Dissolved salts and minerals are small enough to remain in the water after ultrafiltration."
So, am I adding more salt/minerals to our freshwater supply each time I do a water change and dump water down the drain?
Thoughts? Links to helpful articles/research?
Thanks.
