Products for the Control of pH and Conductivity

PH Down
PH Down contains orthophosphoric acid (H3PO4). The concentration is 81% which is very strong so handle with care. Some products on the market are considerably weaker so check the concentration before you buy. This is a very dense liquid and should feel much heavier than water.

PH UP contains potassium hydroxide (KOH). This is a very caustic liquid and should be handled with extreme care. Always check the label before you buy for best value.
