Quick Question About Tap Water

[Blade118]

I was wondering, When during a water change does it matter, if you use tap water from the bathroom or downstairs main tap? Because dont they have a slight PH difference?

Also can you add Pure rainwater to a water change or is that a bad move?

I don't really think it will make a lot of difference which tap you use, (by testing the water samples you will get a better idea)
my tank used to be in my bedroom and at the time i added water from the bathroom, now the tank is in the living room and i use the kitchen tap, personally didn't notice any change between them

Rainwater has a lot of pollutants and nasty chemicals which aren't good to be adding to the fish tank,

Test them both and see if there are any differences.
