HOW LONG WILL MY FILTER CARTRIDGE LAST?
Magnum filter cartridges do not have a defined termination point, but over a period of time your cartridge will gradually block up and will need replacing.
There are three factors in determining whether you cartridge needs replacing:
The cartridge gets blocked quickly, and you have to clean your cartridge more often.
Restricted water flow and high differential pressure (differential pressure is the difference between the pressure coming in and the pressure going out).
A cracked or damaged cartridge (this is very rare, and is usually caused by incorrect installation or high differential pressure).
In a spa or pool with very high usage you will need to change the cartridge within a year, but normally between 18 months and 2 years.
HOW OFTEN DO I NEED TO CLEAN MY CARTRIDGE FILTER?
Because a filter is designed to collect unwanted particles, debris, oils, soaps etc, it will need to be cleaned periodically. Basically the more you use your spa or pool, the more often you have to clean the filter cartridge. From very high usage (every 2-3 weeks) to low usage (every 2 months).
A blocked cartridge can put undue pressure on your pump and motor and decrease the life of these parts.
Please use BioGuard Filter Brite or BioGuard Spa Filter Renew to clean your filters on a regular basis.
