Growth Technology pH DOWN contains orthophosphoric acid (H3PO4). The concentration is 81%, which is very strong so handle with care. Some other 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.
Always wear gloves and eye protection when handling aggressive liquids
Always store in locked cupboards
KEEP AWAY FROM CHILDREN
pH UP and pH DOWN should be diluted before use – ask for the Growth Technology leaflet on pH and Conductivity
