Propher Ph up and down work better. Lemon juice, vinegar, baking soda all work but they don't last as long and will build up in no time at all.

You want to keep your Ph between 5.2-6.0 at all times.
As the plants use up nutrients and deposit others back into the water the Ph will change and should be adjusted twice a day to maintain proper levels.
