The Importance of Circulation, Filtration and Cleaning the Pool Water

Circulation

Circulation is the process of drawing water from the pool through the suction line and forcing water back to the pool through  the filter and pressure/return line. This is achieved with the use of a pool pump. The circulation system has a dramatic affect on the sanitation of a pool and water quality.  When water is in motion, it’s harder for bacteria and algae to find a surface on which to grow and the chemicals are more thoroughly distributed.  In addition, as the water passes through the filter, debris is captured for easy removal, reducing cloudy water.

Filtration

The Filter is the first piece of equipment to receive the water from the pump. The filter strains the water and captures both large and small particles.  A properly sized and operating filter is critical to keeping water clean.  As the filterable debris is collected on the surface of the filter, routine physical cleaning (backwashing and rinsing) is required.  Good maintenance of the filter is essential and always involves two steps:

  • Physical cleaning (backwashing and rinsing) to remove loose debris, performed weekly for effective filtration and circulation
  • Chemical cleaning to remove oils and stubborn, caked-on debris

Chemically clean your filter with BioGuard Strip Kwik!

BioGuard Strip Kwik® removes oils, scale and greases from swimming pool filters to improve efficiency. Typically filter cleaning should be done at least twice a year. For effective filtration we recommend chemically cleaning  the filter at the start and end of each summer season.

Enhancing Filtration

All filter types, can at some time, use the assistance of water clarifying agents to clarify cloudy water, aid in the removal of dead algae and filter out the finer particles that pass through the filter media.

BioGuard’s line of Water Enhancers include products with unique properties to accomplish various task:

  • BioGuard Polysheen Blue® – use as a maintenance product to increase the particle size of debris, so it can be filtered out by the sand filter.
  •  BioGuard Kwik Clear – in addition to its water clarifying capability, it can be use to settle the debris and dead algae to the bottom of the pool for manual vacuum removal to waste.
  • BioGuard Super Clear Clarifying Tablets – a clarifier applied to the weir weekly to remove organic and inorganic particles 

Brushing & Vacuuming

Some swimming pools have areas with little or no circulation. This is where algae and bacteria can begin to grow. At least once a week, the walls and floor should be brushed and vacuumed to prevent problems from occurring. Brushing is a must, even if you use an automatic pool cleaner or retain a weekly pool service. Remember to clean the pump and weir baskets as often as needed to ensure effective circulation and filtration.

Surface Cleaning Products

The oily residue from bathers is likely to form a greasy water line at the water’s surface, especially inside and around the pools interior wall.  Routine chemical cleaning of this residue is important for several reasons:

  • Cleaning prevents this residue from permanently discolouring tile surround/mosaics.
  • This residue can easily become the breeding ground for bacteria.
  • Greasy water lines look bad.
  • Subsequent cleanings will be easier.

BioGuard’s Off the Wall surface cleaner removes normal build-up of greasy dirt and scale with less scrubbing. This formulation is a good multipurpose cleaner.
