Bleach Versus Pool Chlorine
Common pool chlorine is made up of the chemical calcium hypochlorite at about 65 percent strength. The calcium hypochlorite form of chlorine is a solid that is easy to introduce into pool water.

Calcium hypochlorite chlorine is made specifically for water disinfection purposes, especially in swimming pools. Being formulated specifically for pool use is pool chlorine's primary advantage. It can be introduced into a pool as a powder or in tablet form, which eliminates splashing. Tablets are often slow-release, introducing steady but low amounts of chlorine without the need for regular monitoring. However, calcium hypochlorite can be expensive. As of 2017, a 35-pound bucket typically sells for around $100. A 25,000-gallon pool requires 6 1/2 pounds of calcium hypochlorite to reach 10ppm.
