The Pool Calculator takes care of all the math that might come up while you are keeping your swimming pool's water chemistry in balance, telling you exactly how much of each chemical to add. For background on what the various numbers mean, see Basic Pool Chemistry.
For the "classic" view of the pool calculator see Classic Pool Calculator.
