Product Description:
The Crystal Clear GL100 Pool Cartridge Filter is engineered for superior water clarity in pools up to 90,000 litres, delivering fine filtration with minimal maintenance. Using a high-capacity pleated cartridge, the GL100 captures small particles that sand filters often allow to pass through, resulting in noticeably cleaner, clearer water.
Designed for flexibility, the GL100 can be installed as a primary filtration system or used after an existing sand filter to polish the water further. Its UV-resistant housing, integrated pressure gauge, and high-flow internal design ensure consistent performance while reducing strain on your pool pump.
Unlike sand filters, cartridge filtration does not require backwashing, making it a water-efficient solution well-suited to modern pool systems. Maintenance is straightforward simply remove, rinse, and reuse the cartridge.
Ideal for residential pools, commercial spas, and water features, the GL100 combines performance, durability, and efficiency in a compact vertical design.
FAQs
What is a cartridge pool filter and how does it work?
A cartridge pool filter uses a pleated fabric cartridge to physically trap dirt, debris, and fine particles as water passes through it. The pleats dramatically increase surface area, allowing the filter to capture much smaller particles than traditional sand filters. As water flows through the cartridge, contaminants remain trapped in the fabric while clean water returns to the pool.
What makes a cartridge filter better than a sand filter?
Cartridge filters provide finer filtration, typically down to much smaller particle sizes than sand. They also do not require backwashing, which means no water or chemicals are wasted during cleaning. This results in clearer water, lower running costs, and improved efficiencyespecially in pools where water conservation is important.
Can the GL100 cartridge filter be used on its own?
Yes. The Crystal Clear GL100 is designed to function as a stand-alone filtration system for pools up to 90,000 litres, providing full-time primary filtration without the need for a sand filter.
Can this cartridge filter be installed after a sand filter?
Absolutely. The GL100 is commonly installed after a sand filter as a secondary "polishing" filter. In this configuration, the sand filter removes larger debris while the cartridge filter captures fine particles, resulting in noticeably clearer and brighter water.
How often does the cartridge need to be cleaned?
Cleaning frequency depends on pool usage, environment, and debris load. In most residential pools, the cartridge should be cleaned every 2 to 4 weeks. Pools with heavy use, nearby trees, or fine dust may require more frequent cleaning.
How do you clean a cartridge pool filter?
Cleaning is simple:
Switch off the pump
Release pressure using the air relief valve
Remove the cartridge
Rinse thoroughly with a garden hose
Reinstall once clean
No backwashing, chemicals, or special tools are required.
Does the GL100 cartridge filter require backwashing?
No. Cartridge filters do not use backwashing. This saves significant amounts 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 features a high-flow internal design that allows water to pass easily through the cartridge, reducing resistance and lowering strain on the pump. This can contribute to longer pump life and more consistent circulation.
How do I know when the cartridge needs cleaning?
The built-in pressure gauge provides a clear indicator. When pressure rises above the normal operating range (typically 5080 kPa above clean pressure), it's time to clean the cartridge.
Is the GL100 suitable for saltwater pools?
Yes. The Crystal Clear GL100 is suitable for chlorine and saltwater pools, provided water chemistry is maintained within 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, debris load, and cleaning frequency.
Is a cartridge filter suitable for commercial or spa use?
Yes. The GL100 is suitable for light-commercial pools, hotel spas, and water features, especially where fine filtration and water clarity are priorities.
Does the GL100 filter help with cloudy pool water?
Yes. Cartridge filters excel at removing fine suspended particles, making them highly effective for improving water clarity and reducing cloudiness when paired with proper water chemistry.
Is installation complicated?
No. The GL100 uses standard 50 mm (1.5") plumbing connections and includes a mounting base. It integrates easily 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 refresh filtration performance without replacing the full filter unit.
What pool size is the GL100 best suited for?
The GL100 is designed for swimming pools up to 90,000 litres, making it ideal for large residential pools and light-commercial installations.
