Common Water Issues & Solutions

Cloudy Water

Probable Causes

  • Dirty or clogged filter cartridges
  • Excessive bather oils or organic matter
  • Improper or inadequate sanitizing
  • Suspended organic particles or high total dissolved solids (TDS)
  • Overused or old water nearing drain interval

Recommended Solutions

  • Clean filter cartridges thoroughly with FreshWater® InstantFilter Cleaner or FreshWater® Filter Cleaner.
  • Shock the spa with non-chlorine oxidizer or approved spa sanitizer.
  • Test sanitizer level and add sanitizer until reaching recommended operating range.
  • Adjust pH and total alkalinity using FreshWater pH/Alkalinity Up or FreshWater Alkalinity Down.
  • Run jet pumps on clean cycle to circulate water through cleaned filtration.
  • If water is older than 3–4 months (or 12 months on FreshWater Salt System), drain, clean, and refill.

Water Odor

Probable Causes

  • Excessive organic contaminants in water
  • Improper or insufficient sanitization
  • Low pH level

Recommended Solutions

  • Shock the spa with approved sanitizer / oxidizer.
  • Test and add sanitizer to restore proper residual level.
  • Adjust pH with FreshWater pH/Alkalinity Up to achieve the 7.2–7.6 recommended range.
  • If odor persists, drain, clean the spa shell, and refill with fresh water.

Strong Chemical / Chlorine Odor

Probable Causes

  • Combined chlorine (chloramines) level is too high
  • Low pH level accelerating odor release

Recommended Solutions

  • Shock the spa with sanitizer or FreshWater MPS chlorine-free oxidizer to break down chloramines.
  • Adjust pH to the recommended 7.2–7.6 range using FreshWater pH/Alkalinity Up.
  • Leave the spa cover open for 20 minutes with jets running to allow off-gassing.

Musty or Mildew Odor

Probable Causes

  • Bacteria or algae growth on pillows, underside of cover, or plumbing
  • Spa cover underside has absorbed moisture and mildew

Recommended Solutions

  • Shock the spa water with sanitizer.
  • Remove pillows and cover; clean underside of cover with mild baking soda solution or approved vinyl cleaner and allow to dry thoroughly.
  • If problem is visible or persistent inside the water, drain, clean the shell thoroughly, and refill.

Organic Buildup / Scum Ring

Probable Causes

  • Accumulation of body oils, lotions, cosmetics, and environmental grime along the waterline

Recommended Solutions

  • Wipe off scum line using a soft cloth or nylon spa scrubber (avoid household detergents).
  • If buildup is severe, drain the spa. Clean thoroughly and apply FreshWater Spa Shine to protect the dry shell before refilling.
  • Encourage bathers to rinse off lotions and cosmetics prior to entering the spa.

Algae Growth (Green / Slippery Surfaces)

Probable Causes

  • High pH level neutralizing sanitizer effectiveness
  • Low or zero sanitizer residual over extended period

Recommended Solutions

  • Shock the spa immediately with approved sanitizer.
  • Adjust pH with FreshWater pH/Alkalinity Down to bring it into the 7.2–7.6 range.
  • Maintain continuous sanitizer levels and clean filters daily until water is completely clear.

Eye Irritation

Probable Causes

  • Low pH (acidic water)
  • Low sanitizer level allowing chloramine buildup

Recommended Solutions

  • Adjust pH upward with FreshWater pH/Alkalinity Up to achieve 7.2–7.6.
  • Shock the spa with sanitizer to eliminate irritating combined chloramines, and maintain proper baseline sanitizer levels.

Skin Irritation or Rash

Probable Causes

  • Unsanitary water due to inadequate sanitizer
  • Excessive free chlorine level (above 5 ppm)

Recommended Solutions

  • Test water immediately. If sanitizer is low, shock spa and re-establish proper residual.
  • If free chlorine is above 5 ppm, uncover the spa, run jets, and allow sunlight/time to lower the level below 5 ppm before soaking.
  • Shower immediately after soaking.

Surface Stains (Red, Brown, or Green Tint)

Probable Causes

  • Total alkalinity and/or pH too low
  • High iron, copper, or manganese in local source/well water

Recommended Solutions

  • Adjust total alkalinity and pH to target ranges using FreshWater pH/Alkalinity Up.
  • Add FreshWater Stain & Scale to sequester dissolved metals and inhibit surface staining.
  • When refilling from well or municipal sources with mineral content, always fill through a CleanScreen™ Pre-Filter.

Scale Formation (Rough White Deposits)

Probable Causes

  • Total alkalinity and/or pH too high
  • High calcium hardness in source water

Recommended Solutions

  • Adjust total alkalinity and pH downward with FreshWater pH/Alkalinity Down.
  • If scale requires removal, drain the spa, scrub off calcium deposits with a mild non-abrasive cleaner, and coat shell with FreshWater Spa Shine before refilling.
  • Add FreshWater Stain & Scale and balance water carefully upon fresh fill.
Prevention

Three Golden Rules for Alaska Water Care

1. Always Pre-Filter

Alaska well water and municipal feeds often carry dissolved iron, copper, or high mineral loads. Attaching a CleanScreen™ Pre-Filter to your garden hose stops metals before they enter the tub.

2. Clean Filters Monthly

Rinse cartridges with a high-pressure hose nozzle monthly. Use FreshWater® InstantFilter Cleaner to dissolve oils, and replace filters every 3 years with genuine Watkins cartridges.

3. Test Weekly, Balance Early

Keep pH between 7.2 and 7.6. High pH causes scale and cloudy water; low pH corrodes heaters and causes skin irritation. Adjusting promptly prevents major water chemistry resets.
