Baking soda should not be used in most fresh water tanks, the exception is for rift lake cichlids.
Changing pH involves changing other things, The most important of these is KH. Rather that explain all of this i would rather send you to a site which explains it in simple terms for new fish keepers. It should be very eye opening and informative.

After you have read over that information, come back and ask questions.
Incidentally, I will add a bit of crushed coral to any of my tanks with assassin snails or shrimp. I also feed some food with added calcium. But this is the the even wilder fact. I keep a tank with altum angels. The pH is targetted for 6.0 and the water is soft. Despite this, pond snails have managed to colonize it.
You do not want to get a build of of sodium in a freshwater tank. Moreover, sodium will drive the pH towards an equilibrium of 8.2 pH.Sodium bicarbonate, commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO₃. It is a salt composed of a sodium cation and a bicarbonate anion.
