Frequently Asked Questions
Why multiply by 7.48?
One cubic foot of water equals approximately 7.48 gallons, so multiplying your pool's volume in cubic feet (length × width × depth) by 7.48 converts it to gallons, the standard unit for pool chemical dosing.
How is average depth calculated for a pool with a deep end?
For pools with varying depth, average the shallow and deep end measurements, or more precisely, take several depth measurements across the pool and average them for a more accurate total volume calculation.
Is the shock treatment dosage exact?
No, this is a general guideline — actual dosage depends on the specific shock product's concentration and your pool's current chemical levels. Always follow the product label and test your water before and after treatment.
