Sequestering agents


A sequestering agent is a chemical that combines with metal ions to help keep them in solution and prevent them from falling on the pool’s surface and leaving a stain.

These products, which can also be used to control scale buildup, are used mostly for prevention. They won’t remove old, existing stains (that’s a job for a dedicated stain remover), but they will work on potential stains and keep them from becoming visible.
We Recommend:
The Purple Stuff™, High Quality Jack's Magic Salt Solution


Jack's Magic Purple Stuff™ is the stain preventative of choice, and a must product for salt (chlorine) generator pools. Unlike traditional sequestering agents, The Purple Stuff™ works extremely well in high salt and high TDS pools. The Purple Stuff keeps silica in solution while greatly reducing the incidence of cell fouling (scaling) in salt (chlorine) generators. If you have a saltwater chlorine generator - Jacks Purple Stuff™ is for you!

Source water can sometimes be rife with metals, so the use of a preventive sequestering agent is critical.

Metals often are a problem even if they’re not in the source water. For example, iron can find its way into a pool if there is a notable amount of construction in the area or if old pipes are being dug up for renovation.  A sequestering agent will keep the staining at bay, which is important because iron can wreak havoc on a pool’s surface when certain chemicals are added to the water.

“If you get iron in your water and then shock it, it will turn the steps yellow-brown,” Eastergard says. “Then the customer thinks they’re dirty and you’re not cleaning the pool. This stuff just plates onto the shell material, and it can plate onto the plastic fittings.”
