Frequently Asked Questions
How long does it take to fill a pool?
A standard garden hose flows about 8-10 GPM (gallons per minute). A 15,000-gallon pool takes roughly 25-31 hours to fill. Municipal water costs vary from $3-12 per 1,000 gallons.
How much chlorine does my pool need?
Target 1-3 ppm free chlorine. For initial treatment, add 1 oz of liquid chlorine per 500 gallons to raise by ~2 ppm.
