To find out the quantity of bleach to use in your pool, you need to know the chlorine level. You can do this testing through the use of a chlorine pool testing kit. The level of chlorine your pool should attain before being deemed safe for use should fall between 1-3ppm therefore if your pool is not at that level, you need to use bleach to shock the pool.
