5 Ways to Improve Your Spa Filtration
Is your spa filter too small? Having the best spa filtration you can get will not only make your water cleaner and clearer, but will make it safer and easier to manage, with fewer chemicals.
Without further ado, let's get on with it - here are 5 ways you can improve your spa or hot tub filtration. If you have tips of your own to add, leave a comment at the bottom of the post.
Spa Filters with More Square Footage
Some of the more popular spa filters we sell are available in two different square footage. For instance, the HTF-2370 has the same dimensions as the HTF-2390, but the former is 25 square foot of filter surface area and the latter is 50 square feet. This is accomplished by adding more pleats to the cartridge - double the pleats and you double the square footage! Spa filters with more square footage are more expensive, but doubling the surface area will give you longer filter cycles and better overall filtration.
Clean Spa Cartridge with Filter Cleaner
Cleaning your pool filter cartridge is an important task that shouldn't be rushed. Cleaning between each pleats with a garden hose to flush out the dirt and work loose debris in the fabric. To loosen the dirt trapped in the spun polyester fabric, use a filter cleaner before hosing the cartridge clean. Just add the recommended amount to a bucket of water, and soak your cartridge for the time specified. Then hose it clean. Spa filter cleaners loosen mineral deposits, dirt and oils, to allow your cleaning to be much more effective.
Replace Your Spa Cartridge on Schedule
I usually recommend that people replace their cartridge on schedule, every 12 - 24 months. The wide range depends on how often you use your spa, and how often the filter needs cleaning. Spa cartridge filters are not meant to last forever. The fibers loosen, and allow particles to begin to bypass over time. It's a generally accepted notion that you should replace your cartridge after 12-15 cleanings.
Drain Your Spa on Schedule
I usually recommend that people drain their spa on schedule, every 3-6 months. Here too, the range depends on how often you use the spa, how large the spa is compared to usage, and how well the overall water quality and water balance has been. Over time, total dissolved solids can build up which interferes with water balance. Draining the spa also gives you a chance to use a biofilm remover, like Jet Clean to clean the pipes and hoses of bacteria and polish up the spa with a cleaner like Citrabright.
Use Enzymes or Clarifiers
Spa enzymes are a natural product that digests body oils, make-up, soaps and other sticky substances. Added to your spa, it will reduce sanitizer demand and increase your filter cycles while making your filter more effective. These are the same type of enzymes used in cleaning up oil spills in the ocean, so it can handle your little spa or hot tub oil problem. Using a spa clarifier is another way to increase your spa cartridge filtration, by coagulating small particles into larger, more easily filtered clumps.
Some spas and hot tubs have woefully undersized cartridge filters. If you can't upsize the filter, you can use these tactics above to improve your filtration, or to compensate for poor filtration, without resorting to heavy doses of sanitizer.
