The CTX-700 Metal Sequestrant is a swimming pool scale inhibitor and metal sequestrant, designed to help prevent limescale, cloudy water and stains caused by metals, especially iron. It helps protect pool walls, steps, floor, filters, pumps and recirculation circuits, keeping the water more stable and the filtration system in better condition.
What is CTX-700 Metal Sequestrant used for?
The CTX-700 Metal Sequestrant has been developed to control problems linked to hard water and the presence of metals in swimming pool water, helping to prevent limescale deposits and metal staining.
When limescale or metals such as iron precipitate in the water, marks can appear on pool surfaces, the water may become cloudy and deposits can build up inside filters, pumps and recirculation circuits.
Used as a preventative treatment, CTX-700 helps keep these elements stabilised in the water, reducing the risk of scale build-up, staining and loss of filtration performance. It is especially useful for pools filled with hard water, water containing iron or pools with a history of mineral deposits.
Dosage and application of CTX-700 Metal Sequestrant
The CTX-700 Metal Sequestrant should be applied as a preventative treatment, especially at the start of the swimming season or in pools with hard water, iron in the water, recurring stains or scale build-up.
Before applying: check the pool volume and assess the water hardness or possible presence of metals. If the water contains iron, apply CTX-700 before chlorination or any oxidising treatment.
Recommended dosage
- Initial treatment: 2 L per 100 m³ of water at the start of the swimming season.
- Weekly maintenance: 1 L to 2 L per 100 m³ of water, once a week.
- Very hard water: in pools with water hardness above 45 °F and a water temperature of 28 °C, increase the dose by 25% to 50%.
- Note: dosage may vary depending on water hardness, salt content, weather conditions and the characteristics of the pool.
How to apply step by step
- Calculate the pool volume to define the amount of product required.
- Dilute the CTX-700 dose in a container with water.
- Spread the solution evenly across the full surface of the swimming pool.
- Keep the filtration system running during application.
- Repeat weekly maintenance if the pool has hard water, metals in the water or a tendency to scale build-up.
- If the water contains iron, apply the product before chlorination or oxidising treatments.
Important: CTX-700 is a preventative product for limescale and metals. It does not replace pH control, regular disinfection, proper filtration or water testing for hardness and metals.
What to expect after applying CTX-700 Metal Sequestrant
After applying CTX-700 Metal Sequestrant, the product helps keep limescale and metals under control in the water, reducing the risk of cloudiness, staining and mineral deposits.
In pools with hard water or iron in the water, preventative use helps protect surfaces, filters, pumps and recirculation circuits, avoiding build-up that can affect system performance.
After application: keep the filtration system running and monitor the condition of the water, surfaces and filter. In pools with high water hardness or a tendency to metal staining, weekly maintenance may be required.
CTX-700 works mainly as a preventative treatment. If old stains or strongly attached scale deposits are already present, identify the type of stain or deposit first before choosing a complementary treatment.

FAQs about CTX-700 Metal Sequestrant
What is CTX-700 Metal Sequestrant used for?
The CTX-700 Metal Sequestrant helps prevent limescale deposits, cloudy water and stains caused by metals, especially iron. It is mainly recommended for swimming pools with hard water or a tendency to mineral deposits.
Is CTX-700 also a scale inhibitor?
Yes. As well as binding metals in the water, CTX-700 Metal Sequestrant helps prevent scale build-up on pool walls, floor, steps, filters and other pool surfaces.
When should I use CTX-700 in the pool?
Use it when the water has high hardness, contains iron, shows a tendency to staining, becomes cloudy due to minerals or forms scale deposits in equipment and recirculation circuits.
What is the dosage for CTX-700?
As a reference, the initial treatment is 2 L per 100 m³ of water. For weekly maintenance, use 1 L to 2 L per 100 m³. In very hard water, the dose may need to be increased according to the label instructions.
How do I apply CTX-700 Metal Sequestrant?
Dilute the required dose in a container with water and spread the solution evenly across the pool surface, keeping the filtration system running during application.
Should CTX-700 be applied before chlorination?
Yes. When the water contains iron, CTX-700 Metal Sequestrant should be applied before chlorination or any oxidising treatment. This helps reduce the risk of stains caused by oxidised metals.
Does CTX-700 remove old limescale or iron stains?
The CTX-700 Metal Sequestrant works mainly as a preventative treatment, helping to avoid new deposits and stains. If old stains or stubborn scale deposits are already present, the type of stain should be assessed before choosing a complementary treatment.
