Marquis Hot Tub Water Treatment

FOUR KEYS TO HOT TUB WATER CARE

Every hot tub in the world requires basic water testing and balancing each week, along with periodic draining and cleaning a few times per year. Just like the family car, your spa will perform better and last longer when you follow a consistent maintenance routine. Fortunately, owning a Marquis makes it as convenient as possible. Simply follow these four keys to hot tub water care:

1. FILL IT

  • When filling the spa for the first time (or after a drain and clean), make sure the pump plug and the gravity drain are CLOSED.1
  • Verify the shut-off valves (or, "slice valves") are OPEN.1
  • If your local water source is prone to hard water, use a five-stage pre-filter garden hose attachment when filling. (Available from your local Marquis Dealer.)
  • Fill the spa until its water line reaches about two thirds of the way up the skimmer opening.

2. SET IT

  • Set your desired water temperature in the range of 60 to 104 degrees Fahrenheit (16 to 40°C). Follow the directions in your Owner’s Manual, especially during extremely cold weather.
  • The default filtration cycle is one hour twice per day, plus an automatic 30-minute clean-up cycle after each hydrotherapy session. If necessary, increase the length of filtration cycles according to your spa usage habits and bather load.

3. BALANCE IT

4. CLEAN IT


ADDING SHOCK OXIDIZER

Over time, microscopic particles (or, “dissolved organic compounds”) may accumulate in spa water. Shock oxidizer (or, “spa shock”) breaks these down and removes them.

  • Benefits include: Boosted sanitizer efficiency, improved water texture and clarity, and less opportunity for foaming issues. Gentle and non-smelling Marquis® Non-Chlorine Shock Oxidizer is great for weekly use, or may be used more often according to your spa usage habits and bather load.

Adding spa shock after a hydrotherapy session is most common. Otherwise, allow sufficient time for it to circulate. Then, check water balance and sanitizer level again before entering the spa. Other product options include: Marquis® 1-Step Brominating Concentrate Granules for bromine systems, or Marquis® Chlorinating Granules for chlorine systems.

  • Is your hot tub equipped with an ozonator? If so, adding spa shock on a weekly basis is still beneficial, but a lesser amount of spa shock may be used thanks to the work of the ozonator. How so? After passing through the filtration system and heater, filtered water flows past the ozonator’s Mazzei® injector where it mixes with ozone gas (O3). Microbes are neutralized and dissolved organic compounds are oxidized. As the water re-enters the spa, any residual ozone reverts back into oxygen (O2) and the process repeats itself. Thus, sharing the workload of oxidation helps to conserve your spa shock usage.

1European Holiday Park hot tubs have a gravity drain about the size of a garden hose. In addition, they may have a large-diameter gravity drain equipped with a slice valve. If so, this drain slice valve should be CLOSED to keep water in the spa.
