How to change PH of res tank without taking out the water

Hello people. I am mew to hydro. i am curious how do you guys adjust the PH once the water is in the tank? I am adding my nee feed at a PH of 5.5 and it just naturally rises. I will be letting it raise to 6.2 and them bringing it back down to 5.5 and so on. I was just seeing if you guys take the water out of the tank and re adjust or Perhaps add some ph down to a cup of water and mix straight into the res? The only problem with that is i dont want anything to strong close to my root system...
