When Life Gives You Lemons... Use It as pH Down!

Try substituting your chemical based pH down solution with all natural lemon juice. The average pH of lemon juice is about 2.3 and the citric acid in the juice will help lower your pH (at a rate of 1 tablespoon per gallon) to your desired range. You can use either fresh lemons or the concentrate, both will do the trick.
Although not as concentrated as phosphoric acid, citric acid is a great alternative that, due to its organic structure, won’t harm beneficial bacteria or fungi which assist in nutrient uptake.
