    • Base Demand Reagents - BDR

    A base demand reagent, is a chemical solution used in pool and spa water testing to determine the amount of base - like sodium carbonate or soda ash - is needed to adjust the pH to the desired level. It's a key component in maintaining proper water balance, and preventing issues like corrosion or scaling.
