Pool Volume and Chemical Dosage Calculator

The pool volume and chemical calculator determines how much water your swimming pool holds and calculates exact chemical dosages required for routine sanitization and water balancing.

pH too high (pH-Minus needed)

pH corrector dosage: 472 г pH-мінус

100g per 10 m³ alters water pH by approx 0.2

Required chemical dosing

Shock chlorine (granules)

20g per 1 m³ on season opening or cloudy/green water

630 г
Regular slow chlorine (tablets)

1 tablet (200g) per 30 m³ once a week via skimmer/floater

1.1 pcs / week
Algaecide (anti-algae treatment)

10-15 ml per 1 m³ weekly for algae prevention

315 мл

Safe water treatment guidelines

Never mix chemicals directly. Dissolve granules in a bucket of water before pouring around the edges.
Perform shock chlorination at sunset with circulation pump running continuously for 6-8 hours.
Swimming is safe only when free chlorine level drops below 1.0 - 1.5 ppm (mg/L).

How to use

  1. Select the pool shape: rectangular or round/oval.
  2. Enter dimensions: length, width, or diameter in meters or feet.
  3. Input the average water depth.
  4. View calculated water capacity in cubic meters (m³) and liters.
  5. Check recommended chemical dosages for shock, maintenance chlorine, algaecide, and pH adjustment.

Pool Capacity Sizing Formulas

Rectangular volume: Length × Width × Average Depth. Circular volume: 3.1416 × (Diameter / 2)² × Average Depth. 1 cubic meter equals 1,000 liters or ~264 US gallons.

Frequently Asked Questions

How do you calculate pool volume in liters?

Multiply length by width by average depth in meters to get cubic meters, then multiply by 1,000 to convert to liters.

What is the ideal pH for pool water?

Maintain water pH between 7.2 and 7.4 to maximize chlorine efficacy and prevent skin or eye irritation.
