Not gently... I must admit.
I splash, pour, pump, dump, shake, stir, whisk, beat, and spill it. It also gets heated, even boiled, for hours, then chilled rapidly, and occasionally frozen after which it sometimes gets ground up, smacked on the floor, or hammered... Now I think about it, I feel terrible.
+1 on using RO water (bought or self-generated) if your water composition fluctuates much, or contains large amounts of minerals making it unsuitable for brewing (or other uses) as is.
To remove all chlorine within minutes, I stir a
nip, yep, that's 1/2 a smidgen, a 1/4 pinch, 1/64 tsp (think about it, 1/16 of 1/4 tsp !) of Kmeta powder in 5 gallons of water. You could use 1/4 Campden tablet instead, which in some cases could be considered an "overdose." If your water company uses Chloramine to the max, you may need to double the amount, which really isn't all that much to start with.
