Confused about the water in my QT and pond. I fill the pond with a garden hose and the QT with my utility sink. Both of these faucets are on the same copper line in the basement, but the pond is showing as very hard, and the QT as very soft. I didn't worry about it too much because I tested the water in the bags and it came back very soft, so for a transition that worked out great, but I guess I'm going to need to start bringing pond water to the QT for my water changes to harden it up.
So confusing why it's different coming from 2 different points of the same pipe, they're only about 30' feet of pipe apart and it's all copper, it's not like one is all plastic and the other is copper.
