FAQs
How do I know which Hurlcon model my filter housing takes?
Check the model code printed on your existing cartridge or the filter housing itself, such as ZX150, GX100 or QL540. If the code isn't visible, measuring the cartridge's height and width and matching those dimensions against the listings here works just as well.
Are these cartridges genuine Hurlcon parts or an alternative?
These are NZ-made Magnum cartridges manufactured as replacements for Hurlcon and Astral Pool systems, not original Hurlcon-branded parts. They're built to match the fit and filtration of the original housing.
What's the difference between the ZX, GX, QL and CL series?
These series names reflect different Hurlcon and Astral Pool product lines and housing sizes rather than different filtration technologies. The right series depends entirely on which housing your pool or spa system uses.
How often should a pool or spa filter cartridge be replaced?
Cartridges are generally rinsed every few weeks and replaced roughly every 12 to 24 months, though this varies with usage, bather load, and how consistently the water is chemically balanced.
Does an NZ-made cartridge perform the same as an imported original?
Being NZ-made doesn't change the filtration standard, since the cartridge is built to the specifications of the housing it's designed for. Local manufacturing also means stock is readily available without the wait times that come with imported parts.
Can I use a Hurlcon-compatible cartridge in an Astral Viron system?
Several listings here cover both Hurlcon and Astral Viron branding, since Astral Pool Australia owns Hurlcon and shares housings across both product lines. Check the specific listing to confirm which of your systems it's built for.
