Let’s take the mystery out of spa care products, shall we?

  1. Fragrances. We suggest that you don’t add excess liquid perfumes and fragrances to the water because it contaminates the water with an oily slick. It could promote foaming and tub rings. While the filter should cope with it, it adds an unnecessary burden on the system. Use fragrance candles or essential oil diffusers instead.
  2. pH Reducer. Also called pH DOWN. Dry powder is usually sodium bisulphate or soda ash. from $30 to $90 (season). We recommend muriatic acid instead $15/ 4 L to $30/ 8 L (season). Rarely needed in spas.
  3. pH Increaser. Also known as pH UP, Balancer, Alkalinity Increaser. We recommend sodium bicarbonate or sodium carbonate. $15 (season). Rarely needed in spas.
  4. Alkalinity Increaser. Also known as Pool Balancer. Use sodium bicarbonate or sodium carbonate. $15 (season). Rarely needed in spas.
  5. Water Clarifier. Also known as Liquid Flocculent and Water Polisher. For cloudy water. $20 (season) Clarifier coagulates particles that float and are picked up by the skimmer. On the other hand, flocculent coagulates particles that mostly sink to the bottom of the pool for vacuuming. Use CLEAN & CLEAR.
  6. Calcium hardness increaser. Protects against calcium being sucked out of the grouting. Rarely used if the water and hardness (alkalinity) are balanced. $25 (season). Rarely needed in spas.
  7. Defoamer. Also known as Stain Reducer and Enzyme treatment. Helps the filter work better and keeps the scum lines off the side of the spa. $25 (season). Use C-SPA ENZYME non-foaming.
  8. Balancer. Also known as pH and Alkalinity increaser. The objective is to keep the vital components of the water in an optimum state of cleanliness and clarity. $15 (season). Use CLEAN & CLEAR.
  9. Tricolour Chlorine Tabs. Also known as trichloroisocyanuric acid. Has a low pH of 3.0. Contains CYA (cyanuric acid) to protect against chlorine degradation from UV. $60. Most common spa tabs.
  10. Dichlor. Also known as shock.  Dichlor is the only packaged chlorine form suited for spas because although it is a little more expensive, it has near-neutral pH and does not require the addition of a cyanuric acid stabilizer. It is primarily recommended as an occasional shock since it is not available in tablet form. $45 (season)
  11. Bromine Tabs. About 40% Bromine and 15% chlorine. Suited for those with chlorine skin allergies and rashes. Available in tab form. $60 (season)
  12. Oxidizer. There is a difference between oxidizers and sanitizers. A sanitizer is used to destroy disease-causing germs. When you sanitize water, it means you are removing bacteria from your hot tub. On the other hand, an oxidizer uses oxygen to consume the organic waste that bathers bring with them into the hot tub’s water. The oxidizer converts organic waste into harmless gas that is released into the atmosphere.
  13. Shock. Chlorine powder can act as both a shock and as an oxidizing agent to eliminate organic waste. $20
  14. Liquid chlorine is widely used as a shock. Least expensive alternative. $8
  15. Non-chlorine shock does not disinfect the water. It is mainly used as a weekly treatment to oxidize the water and help remove contaminants and thus clear cloudy water. The non-chlorine shock will help your sanitizer work well by creating ‘Free chlorine’ which is the type of chlorine needed to kill bacteria.
  16. C-Pool CLEAN &CLEAR is an all-in-one natural mineral treatment that kills algae and keeps the water clear. It works well with chlorine and bromine tabs and shock. CLEAN &CLEAR reduces the amount of sanitizer required to kill algae and bacteria. Works well with C-SPA.
  17. Enzymes are highly recommended as an inexpensive spa treatment that stops foaming, clarifies water, helps chlorine and bromine work better, reduces odour and tub rings. Not an algaecide or sanitizer. $20 (season) Recommend C-Spa Enzymes non-foaming. See What Enzymes do in a spa.
