Pool Chemical Dosage Calculator
Calculate exact chemical amounts needed for your pool based on volume and current levels
About this calculator
The Pool Chemical Dosage Calculator helps pool owners determine the exact amount of chemicals needed to maintain proper water balance and sanitation. By inputting your pool volume and current chemical levels, this tool calculates precise dosages for chlorine, pH adjusters, alkalinity boosters, and other essential chemicals. This eliminates guesswork, prevents over-dosing that wastes money and damages equipment, and ensures your pool water remains safe, crystal clear, and properly balanced for swimming.
How to use
Enter your pool's total volume in gallons, then input current readings for pH, chlorine, alkalinity, and other relevant chemical levels from your test kit. Select the target levels you want to achieve, and the calculator will instantly display the exact amount of each chemical needed to reach optimal water balance.
Frequently asked questions
How do I determine my pool volume?
Multiply length × width × average depth × 7.5 for rectangular pools. For round pools, use diameter × diameter × average depth × 5.9.
How often should I test and adjust pool chemicals?
Test your pool water 2-3 times per week during swimming season, and daily during heavy use or after storms.
What happens if I add too much chemical?
Over-dosing can cause skin irritation, equipment damage, and cloudy water. Always add chemicals gradually and retest before adding more.
