Regardless of where you live, source water will usually contain impurities that must be addressed. These include metals, minerals and phosphates. Bathers will bring additional impurities in the form of natural body oils, perspiration, various types of cosmetics not to mention the soaps used to wash their bathing suits.

Filtration is the key. Filtration is the process of removing suspended solids, dirt, oils and other impurities from the water. It’s a critical process to keep water clean and clear and often overlooked in spa care. But, regular maintenance is required to keep optimum filter performance. Marquis offers products to keep you ahead of the game and your filter system working as needed.

  • Rapid Action Filter Cleaner - lifts the oils and greases, minerals and scale embedded into the filter to the surface for spraying off with a hose.
  • Water Clarifier - A long chain cationic polymer designed to improve filter performance by coagulating small particulate matter into larger particles to be captured by the filter. This is made specifically for a hot tub and is compatible with every type of sanitizer system.
  • Naturally Clear - This is an enzyme, which is a catalyst that accelerates a chemical reaction. These enzymes encapsulate oils in the water so the filter can capture them then begin to chemically break them down. Naturally Clear helps keep water clear, reduces odors and aids sanitizers.
