Product Description:

The Crystal Clear GL100 Pool Cartridge Filter is designed to provide exceptional water clarity for pools up to 90,000 liters, offering fine filtration with minimal upkeep. Utilizing a high-capacity, pleated cartridge, the GL100 traps even tiny particles that sand filters often miss, resulting in noticeably cleaner and clearer water.

Engineered for versatility, the GL100 can be installed as your main filtration system or used after an existing sand filter to further refine the water. Its UV-resistant housing, built-in pressure gauge, and high-flow internal design ensure consistent performance while reducing stress on your pool pump.

Unlike sand filters, cartridge filters don’t require backwashing, making them a water-saving choice for modern pool systems. Maintenance is simple: just remove, rinse, and reuse the cartridge.

Perfect for home pools, commercial spas, and decorative water features, the GL100 combines performance, durability, and efficiency in a compact, upright design.

FAQs

What is a cartridge pool filter and how does it work?
A cartridge pool filter uses a pleated fabric cartridge to physically block dirt, debris, and fine particles as water flows through it. The pleats greatly expand the surface area, allowing the filter to capture much smaller particles compared to traditional sand filters. As water passes through the cartridge, contaminants are trapped, and clean water returns to the pool.

What makes a cartridge filter better than a sand filter?
Cartridge filters offer finer filtration, typically capturing smaller particles than sand filters. They also eliminate the need for backwashing, which saves water and chemicals. This leads to clearer water, lower operating costs, and greater efficiency, particularly in areas where water conservation is a priority.

Can the GL100 cartridge filter be used on its own?
Yes. The Crystal Clear GL100 is made to work as a complete filtration system for pools up to 90,000 liters, providing constant, primary filtration without needing a sand filter.

Can this cartridge filter be installed after a sand filter?
Definitely. The GL100 is often installed after a sand filter as a secondary “polishing” filter. In this setup, the sand filter removes larger debris, while the cartridge filter captures the finer particles, leading to significantly clearer and brighter water.

How often does the cartridge need to be cleaned?
Cleaning frequency depends on pool usage, the surrounding environment, and the amount of debris. For most residential pools, cleaning the cartridge every 2 to 4 weeks is sufficient. Pools that are used frequently, near trees, or exposed to fine dust may need more frequent cleaning.

How do you clean a cartridge pool filter?
Cleaning is easy:

Turn off the pump

Release pressure using the air relief valve

Remove the cartridge

Thoroughly rinse with a garden hose

Reinstall once clean

No backwashing, chemicals, or special tools are needed.

Does the GL100 cartridge filter require backwashing?
No. Cartridge filters don’t use backwashing. This saves a lot of water and prevents chemical loss, making them more environmentally friendly and cost-effective than sand filters.

Will a cartridge filter reduce pump strain?
Yes. The GL100 has a high-flow internal design that allows water to easily pass through the cartridge, reducing resistance and strain on the pump. This can help extend the pump’s life and provide more consistent water circulation.

How do I know when the cartridge needs cleaning?
The built-in pressure gauge provides a clear indication. When the pressure rises above the normal operating range (usually 50–80 kPa above the clean pressure), it’s time to clean the cartridge.

Is the GL100 suitable for saltwater pools?
Yes. The Crystal Clear GL100 works well with both chlorine and saltwater pools, as long as the water chemistry is kept within the recommended ranges.

How long does a cartridge filter cartridge last?
With proper care and regular cleaning, a cartridge typically lasts 12 to 24 months, depending on pool conditions, the amount of debris, and how often it’s cleaned.

Is a cartridge filter suitable for commercial or spa use?
Yes. The GL100 is suitable for smaller commercial pools, hotel spas, and water features, especially when fine filtration and clear water are important.

Does the GL100 filter help with cloudy pool water?
Yes. Cartridge filters are excellent at removing tiny suspended particles, making them very effective at improving water clarity and reducing cloudiness when combined with correct water chemistry.

Is installation complicated?
No. The GL100 uses standard 50 mm (1.5″) plumbing connections and includes a mounting base. It easily fits into new or existing pool filtration systems.

Can I replace the cartridge without replacing the housing?
Yes. Replacement cartridges are available separately, allowing you to renew filtration performance without replacing the entire filter unit.

What pool size is the GL100 best suited for?
The GL100 is designed for swimming pools up to 90,000 liters, making it ideal for large residential pools and smaller commercial setups.
