Water pH question

Hello yes you can use both vinegar is acetic acid so you can and lemon juice works too. Citric acid but you have to be careful with doses. Finally you want to raise ph you can use baking soda if you put too much vinegar or lime. The best stay to buy a bottle of ph down because there is components which regulate and stabilize your Ph. So you can do it yourself or buy a bottlle. Good luck brother. Bye
