My tank temp is 79 F but my room temp is 72 and there’s no heater in the tank. What’s going on? Could the air from the air pump be warming the tank? Thanks

Reentering the hobby after many years

I've read the article on cycling a tank before adding fish and I'm wondering why is it recommended to do a "water change" after ammonia and nitrate read zero and just before adding fish?  Also please define "water change" -- how much and how to do it.   Thank you very much, webunit
