Problem Usual Cause Solution
Cloudy Water
– Inadequate filtration/dirty filter

– Excessive oils/organic matter

– Improper sanitation/bacteria

– High pH and/or high alkalinity

– Check to make sure the filter is running properly; clean filter with a filter cleaner of degreaser

– Shock the spa with a chlorine or bromine sanitizer, or other shock treatment product

– Increase sanitizer level to balance water and shock if needed

– Adjust pH; add appropriate sodium bisulfate product

– Use clarifier

NOTE: If using an ozone generator of Clean Zone™, consult with your dealer before using polymer based clarifiers
– Depending on the severity, drain the spa completely, clean and refill

Water Odour  – Excessive organics or chloramines; insufficient free available sanitizer- Improper sanitizer- Inadequate filtration- Low pH – Shock the spa with a chlorine or bromine sanitizer/shock, or other shock treatment product- Increase sanitizer level to balance water; shock if needed- Check to make sure the filter is running properly; clean filter with a filter cleaner or degreaser- Raise pH with sodium bicarbonate product. If metals are present, add chelating agent.
Chlorine Odour  – Too many chloramines/insufficient free available chlorine- Low ph  – Shock the spa with a chlorine available chlorine sanitizer/shock, or non-chlorine shock treatment- Adjust pH; raise pH with sodium bicarbonate product
Bromine Odour/Yellow Water – Low pH  – Adjust pH; raise pH with sodium bicarbonate product
Musty Odour  – Bacterial or algae growth  – Shock spa with a chlorine or bromine sanitizer/shock, or equivalent shock treatment product. If problem is visible, drain, clean.
Foaming/Scum Ring Around the Tub  – Build up of body oils, lotion and chemicals resulting from soap or detergent  – Skim foam off using your leaf net or, drain and refill
Skin Irritation/Rash  – Low pH- Insufficient free available chlorine  – Raise pH with sodium bicarbonate product- Shock with a chlorine sanitizer/shock or other shock treatment product
Scale  – Too much calcium dissolved in water pH and total alkalinity too high  – Add a scale control product. Adjust total alkalinity and pH levels by adding the appropriate sodium bisulfate product; for concentrated scale deposits- Drain spa, scrub scale off, refill the spa and balance the water
Erratic pH Test Results/Unusual pH Test Colour  – Sanitizer level too high- Old pH indicator dye  – Test the pH, when the sanitizer level is below 5 ppm- Replace the pH indicator dye
Sanitizer Dissipating Too Rapidly  – Excessive organics in water- Temperature too high- Low pH- Low pH corrosion of metal fixtures- Low calcium hardnessLow total alkalinity  – Increase shock dosage; add sanitizer;shower before entering spa– Reduce temperature- Raise pH with sodium bicarbonate product- Use chelating agent if metals are present. Maintain minimum 150-200 ppm calcium hardness- Use chelating agent if metals are present. Maintain proper alkalinity for type of sanitizer used.
