I just started a new small 5gal freshwater tank... but i've been having issues figuring out what water to use for water changes. Some people say treat the tap water, some say use bottled water and/or treat that aswell, then there are still others saying use distilled or RO and add aquarium salts to it.
With so much info and little to base it on, what to you all think is best to use?
