What And How Sequestering Agent Works on Pool

Sequestering agents are generally used to reduce water hardness. A sequestering agent is an organic compound that can link metal ions together to form a complex ring-like structure. 

Generally, the sequestering agent holds iron, manganese, copper, and calcium in the solution. As a result, they never react with other elements in the water. 

When you apply the sequestering agent, it binds metal ions from your pool until they filter out. As a result, stains and scales fail to stand on your pool surfaces and walls. Indeed, sequestering agents help keep your pool crystal clear by controlling the stains & scales. However, if you are dealing with calcium deposits in your pool, there are a few ways to handle it.
