Description
Overview
The Magnum pool filter cartridge for the Poolstore Bowman C0755 is a New Zealand-made replacement built to the exact dimensions of the original Bowman C0755 housing. At 177mm outside diameter and 455mm in length, with a moulded knob handle on the top end cap and a moulded cone base, it seats firmly and filters consistently without the guesswork that comes with an approximate fit.
For residential pools, consistent filtration across the swimming season matters more than anything else. A correctly sized C0755 cartridge maintains steady water flow, helps keep pump pressure within normal operating range, and makes weekly maintenance straightforward rather than a process of working around a poorly fitting element.
This cartridge is stocked specifically for Bowman C0755 systems and is not a generic approximation. If your filter housing calls for a C0755, this is the direct replacement.

Where to Use This Cartridge
This cartridge is the correct replacement element for Poolstore Bowman C0755 cartridge filter housings. It suits home pools where the priority is clear water, efficient pump operation, and a straightforward maintenance routine. It is not suited to systems specifying a different Bowman model number, as end cap configuration and dimensions vary between Bowman housing sizes.
If you are unsure which cartridge your system requires, check the label on your filter housing or refer to your original installation documentation. The C0755 designation should appear on the housing itself.
How to Install
-
Switch the pool system off at the pump and allow pressure to drop before opening the filter housing lid.
-
Remove the old C0755 cartridge and rinse the inside of the housing to clear any settled debris.
-
Lower the new cartridge into the housing, ensuring the cone base sits flat in the seat, and the element is centred.
-
Refit the housing lid and tighten it securely.
-
Restart the pump and check the pressure gauge. Normal operating pressure should return within a minute or two of startup.
Maintenance and Cleaning
The Bowman C0755 cartridge can be removed and rinsed multiple times over its working life. For routine cleaning, switch off the pump, remove the cartridge, and rinse it thoroughly with a garden hose, working from the inside of the pleats outward. Avoid high-pressure washing, which can damage the filter media.
For a deeper clean after heavy use or at the start of a new season, soak the cartridge overnight in a diluted cartridge cleaning solution before rinsing. This removes oils, sunscreen residue, and fine particles that rinsing alone cannot shift.
Even with regular cleaning, cartridge media gradually loses its ability to filter effectively. Once cleaning no longer restores normal flow and pressure, replacement is the right call rather than continuing to run the pump harder to compensate.

Frequently Asked Questions
Is this a direct replacement for the Poolstore Bowman C0755?
Yes. The dimensions, end cap configuration, and filter media are matched to Bowman C0755 housings. It seats correctly and replaces the original element without modification.
Is this cartridge made in New Zealand?
Yes. Magnum cartridges are manufactured in New Zealand.
How often should I replace my C0755 pool filter cartridge?
Most home pools replace their pool filter cartridge every one to two seasons. Frequency depends on pool usage, bather load, and how regularly the cartridge is cleaned. A cartridge that climbs to high pressure quickly, even after cleaning, has reached the end of its useful life.
Can the C0755 cartridge be cleaned and reused?
Yes. It can be rinsed and cleaned multiple times. Once cleaning no longer restores adequate flow or pressure returns to normal levels, replacement is recommended.
What happens if I use the wrong size cartridge in a Bowman housing?
A cartridge that does not match the housing dimensions will allow water to bypass the filter media, reducing filtration effectiveness. It can also affect the flow rate and put unnecessary load on the pump motor over time. Using the correct C0755 replacement avoids these problems.
How do I know when my pool filter cartridge needs replacing rather than cleaning?
The clearest sign is pressure that builds back up quickly after cleaning, or water clarity that does not improve even with a clean cartridge in place. If rinsing and soaking no longer restore normal pressure and flow, the cartridge should be replaced.
Pro Tip
Keeping a spare C0755 cartridge on hand means you can rotate elements during the season. While one cartridge soaks overnight in a cleaning solution, the other keeps the pool running. Over time, this approach extends the life of both cartridges and reduces the chance of being caught without filtration during peak swimming months.
