So, how many gallons of bleach would you need to shock your pool? First, you should know the level of chlorine in your swimming pool.
You can easily do that by testing the water using a chlorine testing kit – make sure you follow the manufacturer’s guide. The aim is to hit a chlorine level of 1-3 ppm to ensure that your pool remains safe for the swimmers and free of contaminations.
As an example, Clorox is mainly used as a bleach in the swimming pool. That product features 5.7% concentration, and that means you would need to add 24 oz or 3 cups in a 5,000 gallons pool to boost the chlorine levels.
Finding the Volume of Pool
If you don’t know how much water your swimming pool holds, multiply its length by its width and then by the relative depth of the pool. You will get an estimate volume.
If it is a round pool, multiply the estimated volume by 5.9, by 6.7 for an oval facility, and by 7.5 for a rectangular one. The result you get will be the amount of water your swimming pool hold.
