Hot tub owners often have many questions about the care and maintenance of spa filter cartridges, and it can seem confusing to try and figure out all of the steps that need to be taken to ensure that the hot tubs continue to run smoothly and that they stay clean. From pH of the water to choosing the right cover and everything in between, hot tubs require work. However, when dealing with spa filter cartridges, everything else can fall into place pretty easily when they are properly taken care of. Here are some of the most common questions about the filters and the answers that can help owners with maintenance and upkeep.
FAQ #1: When should a filter cartridge be cleaned?
A: Establishing a routine cleaning schedule is recommended, and owners should establish one based on the amount of time that the hot tub is used for. Those that are used very often would of course require more upkeep, while those that are used every once in a while may not need so much. Most professionals suggest that a rotation pattern be used, moving the cartridges clockwise about every other week. Start with a cartridge and label it 1, and when it reaches spot 3 (for example) and sits there for a week or two, the next time you rotate them, toss that one out and replace the one in slot number 1 with a fresh new one.
FAQ #2: How do I go about cleaning my cartridge?
A: The first step is to take the spa filter cartridges out of its housing according to the manufacturers instructions. You can use a garden hose to wash down the filter; hold the nozzle at a 45 degree angle, and wash in between all of the pleats if you have a pleated unit. Do NOT use a power washer or put it in the dishwasher! Keep rinsing until all of the debris and dirt have been removed. You can choose to soak it overnight in a commercial filter cleaner, too. If you do this, be sure to rinse it again to remove the cleaning solution. You can then store it as a spare or reassemble it into its housing.
FAQ #3: What do I need to know about cleaning spa filter cartridges with a biguanide system?
A: These systems destroy bacterial cells unlike chlorine, which oxidizes them. These systems act as coagulants too, which means that the bacteria and other dirt and debris clump together into particles that are large enough for the filters to trap. What you will see on your spa filter cartridges from this is a gray sticky film, so youll need that special cleaner to remove it. If tri sodium phosphate is used before cleaning, the cleaner and the gray film will combine and turn gummy, which then means that the spa filter cartridges are no longer usable and they must be replaced, so be aware of this possibility.
