How Do You Raise Hydro PH?

How would be the most effective way to raise the PH from like 4.5-5 to 5.5-6 in a 5 gallon Hydro setup.

pH up..........

Too potent.

just put one drop at a time

lol

just literally grab a needle and dip that in, shaking it off on the inside lip of the bottle before you dunk it

your right about the potency, dont let that intimidate your judgement though
