Hot Tub Maintenance with SPA MARVEL

Initial Start-Up: For Greater Victoria Tap Water (for 1,000 Litres Hot Tub – for 1,500 Multiply by 1.5)

SPA MARVEL CLEANSER - Remove Filters. Pour one bottle of Spa Marvel Cleanser into existing water. Allow Cleanser to circulate in water with jets on High for At Least 1 hour and then Circulate on low speed for an additional 23 hours. Drain and flush the tub. Rinse thoroughly.

Before adding chemicals, know your spa water capacity in litres.

  1. Add 12g or 2 tsp. of SM BRITE (non chlorine shock and bromine booster) per 1000 litres .

  2. Once the spa has sufficient water for circulation, turn on the filtering equipment.
  3. Add appropriate amount of CLARIFIER : 15 ml/1000L (CLARIFIER) or 1 tsp./1000L for CLEAR 4-in-1 Clarifier.
  4. Add 60g of ALKALINITY and 350 ml (205g) of CALCIUM per 1000 litres.
  5. Using Bromine or Chlorine, add appropriate amount of sanitizer. (6g or 1 tsp. of SANI BROM per 1000 litres)
    The skimmer basket can also be used to dispense Tablets.

  6. Using 4 Part Test Strips:
  • Test the total alkalinity. The ideal range is 100 – 150 p.p.m. Adjust with ALKALINITY or MINUS GEL (PH-)
  • Test the pH. The ideal range is 7.2-7.8. Adjust if necessary with PLUS GEL (PH+) or MINUS GEL (PH-)
  • Test and adjust the water hardness. Adjust with CALCIUM to 100 - 200 p.p.m.
  1. SPA MARVEL TREATMENT & CONDITIONER: Bring up to normal temperature then add one bottle of Spa Marvel. One bottle of Spa Marvel will treat up to 2000 litres. One bottle of Spa Marvel will last up to 3 months depending on bathing loads. With Spa Marvel, you can leave your existing water in for up to a year!

Filtration Settings can vary from tub to tub and depending on bathing loads. Ensure filtration is set appropriately.


Minimum Weekly Maintenance (depending on bathing loads)

  1. Test pH to maintain a level of 7.2-7.8 and alkalinity 100-150 p.p.m.
  2. Adjust sanitizer to appropriate levels. Minimum Chlorine 1 p.p.m. Minimum Bromine 3 p.p.m.
  3. Add 1 Tablet of sanitizer or 1 tsp. (6g) of SANI BROM per 1000 litres.
  4. Using 4 Part Test Strip:
  • Test and adjust Bromine, pH ( PLUS GEL (PH+) or MINUS GEL (PH-) and Alkalinity (ALKALINITY).
  • Using BROMINE TABLETS test for Bromine and adjust feeder to maintain a bromine residual of 3 p.p.m.
  1. SM BRITE (Non Chlorine Shock): 12g/1000 litres - Hot tub is safe to use 15 minutes after using SM BRITE.


Monthly Maintenance

  1. Greases, oils and organic waste can accumulate on the filter cartridge reducing efficiency and limiting the effectiveness of the sanitizer. Clean the filter with your choice of filter cleaner as directed (CITRA-CLEAN, Spa Marvel Filter Cleaner or CONTACT). Physically clean the basket daily. The use of SPA PERFECT will prolong the life of the filter cutting down on grease, foam and suspended particles in the hot tub.

  1. WHEN TO DRAIN SPA WATER: With Spa Marvel you can often go up to a year without changing your water. You do not need to change it as often as you typically would as you are not super-saturating the water with all kinds of chemicals on a routine basis and the TDS (total dissolved solids) of the water increases only marginally. For best results do not go over a year without changing the water. Water will wear out after a year and you will have difficulty maintaining the pH.
