Sequestrant Pool: Swimming Pool Metal Control and Stain Removal

When you own a swimming pool, you always have to check the chemical composition weekly to ensure the water is habitable. When reviewing its chemical composition, you test for calcium hardness, total chlorine, and pH level.

Checking the pool weekly can help prevent problems that lead to discoloration from algae or metals. But if you don’t review these chemicals, your pool can be affected by these metals or algae such as iron turning the water brown or greenish or copper, causing the water to become green in color the same as algae while manganese would cause the walls to have black stains. If these stains occur, they can be eradicated by a pool sequestrant.

Why make use of sequestrant for pool water?

A sequestrant for pool water is a chemical that binds liquefied metal salts in a pool. It can be added to your cleaning solution to;

  • To stop hardness ions such as calcium or magnesium from precipitating and
  • To break down the scale on the surface of the pool

While acids can break down scales on its own, neutral cleaning agents and alkaline need sequestrant material to provide hardness of ion and to clean the pool. Stoichiometric sequestrants or sequestrant molecules bound the models that ensure the hardness of ion.

While other sequestrants are threshold cleaners. They are made of molecules that prevent the growth of scales crystals in solutions so that few sequestrant molecules can stabilize a large number of scale creating ions.
