   [
   \text{Length} \times \text{Width} \times \text{Average Depth} \times 7.48 = \text{Gallons}
   ]
   For round pools, use:
   [
   \text{Radius}^2 \times \text{Average Depth} \times 3.14 \times 7.48 = \text{Gallons}
   ]
2. Determine Desired Chlorine Level: Decide the target ppm. For example, if you aim for 3 ppm, note this down.
3. Calculate Chlorine Needed: Use this formula to find how much liquid chlorine to add:
   [
   \text{Amount of chlorine (in gallons)} = \left(\frac{\text{Pool volume (gallons)} \times \text{Desired ppm increase}}{10}\right)
   ]
   Here, 10 represents the chlorine effectiveness of a 10% solution.
4. Add Chlorine: Pour the calculated amount of liquid chlorine into the pool, preferably in front of a return jet to help distribute it evenly.
