Key Fit & Function Professional-grade stain & scale preventer for swimming pools Sequesters dissolved metals (iron, copper, manganese) to prevent surface staining Helps prevent calcium scale formation on pool surfaces and equipment Ideal for hard water conditions and pools with metal content Compatible with chlorine and saltwater pools when used as directed 32 oz bottle (SKU 71016A) suitable for routine maintenance dosing Metal staining and scale buildup don’t happen overnight—but once they show up, they’re difficult and expensive to remove. GLB Sequa-Sol 32 oz is a professional-grade sequestrant designed to stop those problems before they start by keeping metals and minerals dissolved and inactive in pool water. Whether your fill water contains iron, copper, or calcium, Sequa-Sol works at the chemical level to bind and hold dissolved metals, preventing them from oxidizing and depositing on pool surfaces, plumbing, heaters, and salt cells. Used as part of a regular maintenance routine, it protects your pool’s appearance, extends equipment life, and keeps water looking clean and uniform. This is a preventative product, not a stain remover—making it most effective when used proactively or immediately after metal introduction. How GLB Sequa-Sol Works Metals and minerals enter pools from source water, corrosion, algaecides, heaters, and plumbing components. When these elements oxidize, they fall out of solution and attach to plaster, vinyl, tile, and fiberglass—creating brown, green, or gray stains and hard scale deposits. GLB Sequa-Sol uses a high-quality sequestrant formula that chemically binds metals and calcium, keeping them suspended in the water so they can pass safely through the filtration system instead of attaching to surfaces. Because sequestrants slowly break down over time, consistent maintenance dosing is essential for ongoing protection. Why Stain & Scale Prevention Matters Once staining or scale forms, removal often requires aggressive treatments that can disrupt water balance, damage surfaces, or shorten equipment life. Preventing the problem is always easier—and safer—than fixing it later. Why It Matters Prevents metal staining on plaster, vinyl, and fiberglass Reduces scale buildup on tile lines and heaters Protects salt cells and plumbing components Helps maintain uniform water appearance Minimizes costly corrective treatments Sequa-Sol is especially important in areas with hard water or known metal content, where staining issues are common. Ideal Use Cases for GLB Sequa-Sol GLB Sequa-Sol is effective in both residential pools and professionally maintained systems where metals and minerals are a known concern. Best Times to Use After adding fresh fill water At pool startup or seasonal opening After metal-based algaecide use When using well water or hard municipal water As part of a regular weekly or monthly maintenance routine It can also be used alongside stain removal treatments to keep metals in solution after stains are lifted. Safe for All Pool Types & Systems GLB Sequa-Sol is compatible with: Chlorine pools Saltwater pools Vinyl, plaster, fiberglass, and tile finishes Heaters, salt cells, and standard filtration systems It does not affect pH when used as directed and integrates easily into existing maintenance programs.
