To chlorinate a 20x40 pool, you typically need about 1-3 pounds of chlorine per 10,000 gallons of water to achieve the recommended chlorine level. Assuming an average depth of 4 feet, the pool holds approximately 27,000 gallons of water. Thus, you would require about 2.7 to 8.1 pounds of liquid chlorine to reach the desired levels, depending on the current chlorine concentration and water conditions. Always test the water first and adjust accordingly.
Clorine is dangerous, see this website: http://www.kewego.com/video/iLyROoafY8DO.html And here is how I handle my Pool: http://live-efficient-green.blogspot.com/2009/07/pool-with-no-harmfull-chemicals.html Hope this helps.
Area of deck = (20+2d)x(40+2d)-(20x40) Area of deck = (20x40)+40d+80d+4d2 -(20x40) Area of deck = 120d+4d2
Close to 24,000 gal if it is rectangular.
Chlorine*
because it has clorine
Chlorine has been linked to asthma in young children.
Cross multiply then divide, 20*8 divided by 40= 40 gallons
clorine
dont use soap use clorine
5200 cubic feet
about 5 min. if it's only 1" deep, depending on water pressure.
There is no such thing.
