Pool Volume Calculator — Gallons & Chlorine Dose

How the pool volume calculator works

Volume = length × width × average depth × 7.4805 (gallons per ft³). 1 oz of 12.5% liquid chlorine per ~10,000 gallons raises free chlorine by ~1 ppm.

A 15×30 ft rectangular pool with 5 ft average depth holds ~16,835 gallons.

To raise FC by 5 ppm in 15,000 gallons: ~75 oz (about 2.3 quarts) of 12.5% liquid chlorine.
