Liquid Chlorine (12.5%) vs Pool Volume

Formula

Pool Chlorine Dosing

Maintaining proper chlorine levels (1-3 ppm for residential pools) requires calculating the right dose based on pool volume and current levels.

Simplified Dosing

Liquid Chlorine (12.5% sodium hypochlorite): ~1.3 mL per gallon per 1 ppm increase

Granular Chlorine (65% calcium hypochlorite): ~0.24 grams per gallon per 1 ppm increase

Always add chemicals to water, never water to chemicals. Add in the evening when UV degradation is minimal.

Exemplo Resolvido

A 15,000-gallon pool needs chlorine raised from 1 to 3 ppm.

  1. 01PPM increase = 3 - 1 = 2 ppm
  2. 02Liquid chlorine = 15,000 x 2 x 0.0013 x 128 = 4,992 fl oz = ~39 fl oz
  3. 03Granular chlorine = 15,000 x 2 x 0.00024 x 16 = 115.2 oz = ~7.2 oz

Perguntas Frequentes

What is the ideal chlorine level?

Residential pools: 1-3 ppm free chlorine. Hot tubs: 3-5 ppm. Below 1 ppm risks bacterial growth; above 5 ppm can irritate skin and eyes.

Why does my chlorine disappear?

UV sunlight destroys chlorine rapidly. Use cyanuric acid (stabilizer) at 30-50 ppm to protect chlorine. Heavy bather load and organic debris also consume chlorine.

How do I calculate pool volume?

Rectangular: Length x Width x Avg Depth x 7.5 gallons. Round: Diameter² x Avg Depth x 5.9 gallons. Oval: Long Diameter x Short Diameter x Avg Depth x 5.9.
