GLB Pool & Spa Sequa-Sol Sequestering Agent (1 qt) – Pack of 2
Features: Protects pool equipment and surfaces from stains, scale and rust. Compatible with chlorine, bromine, biguanide, ozone and salt water sanitizing systems. 2 Pack. This product is best for pools with mixed sanitizers or salt systems where mineral control is critical.
Best for: Pool owners looking for an easy-to-use weekly sequestering solution that works across common sanitizer systems. This option is well suited for maintenance routines and can help extend surface aesthetics and equipment longevity.
Caution: Effective dosing depends on pool volume and water chemistry. Follow label directions for openings or refilling periods to maximize benefits.
Pool Mate 1-Quart 4-Pack Concentrated Metal Out Stain and Mineral Inhibitor
Features: 1 quart per 10,000 gallons of water. Helps remove and prevent calcium, cobalt, copper, iron, lead, manganese, nickel and silver. Prevents discoloration from metals and minerals in the water supply. Made in USA.
Best for: Pools with noticeable mineral content or ongoing staining concerns caused by iron, copper, or other metals. This product is ideal for larger volumes when metal buildup is a recurring issue.
Limitation: Requires proper dosing for your pool size; under-dosing reduces effectiveness in hard water scenarios.
Pool Mate 1-Quart Concentrated Metal Out Stain and Mineral Inhibitor (1 qt)
Features: 1 quart per 10,000 gallons. Helps remove and prevent calcium, cobalt, copper, iron, lead, manganese, nickel and silver. Prevents discoloration from metals and minerals in the water supply. Made in USA.
Best for: Similar use case to the 4-pack variant but suitable for households with smaller pools or where a single quart suffices for maintenance cycles.
Limitation: Like other metal inhibitors, effectiveness depends on consistent dosing and accurate pool volume measurement.
GLB Sequa-Sol Pool Stain Preventer (1 qt) – 6 Pack
Features: Sequa Sol provides fast protection against staining and scaling. Use as part of weekly maintenance. Can be added to pool water anytime, recommended at pool opening or first fill.
Best for: Pools entering the season or newly filled pools needing immediate protection against early staining and scaling. Suitable for ongoing maintenance cycles.
Caution: Best results come from integrating Sequa-Sol with a regular maintenance plan and water testing routine.
GLB Sequa-Sol Sequestering Agent – 12 Pack
Features: Provides fast protection against staining and scaling. Useful for weekly maintenance and at pool openings or initial fill. 12-pack offers bulk convenience for larger facilities or long-term use.
Best for: Larger homes or facilities needing bulk stock and consistent mineral control across multiple maintenance cycles. It supports ongoing stain prevention with less frequent reordering.

Limitation: Dose according to pool size to maintain effectiveness over time.
LO-CHLOR LO-MG-1 Sequestering Agent
Features: Sequesters and removes metals by forming complexes (chelates). Regular use prevents new stains and reduces older metallic stains. Aids in scale removal and prevention.
Best for: Pool owners who want a straightforward chelation approach to ongoing metal prevention and scale management. Good for routine maintenance in varied water chemistries.
Caution: Chelating agents rely on correct dosing; excessive use can alter water balance if not monitored.
Buying Guide: Key Considerations For Choosing A Sequestering Agent
- Pool size and water volume: Match product packaging to gallons to avoid under- or over-dosing.
- Water chemistry: Consider metals present (iron, copper, manganese) and whether your water is hard or softened.
- Sanitizer compatibility: Ensure the product works with your sanitizer system (chlorine, bromine, saltwater systems, etc.).
- Maintenance frequency: Choose packs that align with how often you perform maintenance openings, refills, or seasonal starts.
- Storage and handling: Bulk packs require proper storage and rotation to prevent degradation.
- Ease of use: Some products are designed for flexible dosing at any time, while others are best at openings or first fills.
FAQ
- What is a sequestering agent in pool care?
A sequestering agent binds metals in pool water to prevent them from forming stains or scaling on surfaces and equipment.
- How do I know how much to use?
Follow the label based on your pool’s gallons and water chemistry; mis dosing can affect balance.
- Can I use more than one sequestering product at a time?
Avoid mixing different products unless the labels explicitly allow it; consult the product guidelines first.
- Which sequestering agent is best for hard water?
Products designed for metal removal and mineral inhibition with broad compatibility (like GLB Sequa-Sol variants) are commonly recommended for hard water.
- When should I add Sequa-Sol at pool opening?
It’s often advised to add at opening or when filling a new pool to prevent early staining and scaling.
- Is a sequestering agent the same as a metal remover?
Metal removers chemically remove metals; sequestering agents keep metals in solution and prevent staining, usually used together for best results.
