Could I use rain water for a top off? I have no acid rain where I live and it rains alot.
RYANLAWRENCE said:All rain water is acidic to varying degrees. Some rain might be very close to a pH of 7, but I would say 90% of rainfall in America is actually pretty acidic thanks to pollution. Rainwater actually has a lotta stuff that you don't want in it and remember, just because you live in a pollution free area doesn't mean that the cloud where the rain came from was pollution free
