Probable Cause

Solution

Dirty filters

Clean filters with a Filter Cleaner.

Excessive oils/organic matter

Shock spa with Concentrated Chlorinating Granules or a Spa Shock.

Improper sanitization

Add sanitizer (such as Chlorine or Bromine).

Suspended particles/organic matter

Adjust pH and/or alkalinity with a pH/Alkalinity Increaser or pH/Alkalinity Decreaser.

Overused or old water

Run jet pump(s) and clean filter(s) with a Filter Cleaner.

Drain, clean, and refill the spa.

Probable Cause

Solution

Excessive organics in water

Shock spa with Concentrated Chlorinating Granules or a Spa Shock.

Improper sanitation

Add sanitizer (such as Chlorine or Bromine).

Low pH

Adjust the ph with a pH/Alkalinity Increaser.

Probable Cause

Solution

Chloramine level too high

Shock spa with Concentrated Chlorinating Granules or a Spa Shock.

Low pH

Adjust pH and/or alkalinity with a pH/Alkalinity Increaser or pH/Alkalinity Decreaser to recommended range.

Probable Cause

Solution

Bacteria or algae growth

Shock spa with Concentrated Chlorinating Granules or a Spa Shock.
- if the problem is visible or persistent, drain, clean, and refill the spa.

Probable Cause

Solution

Buildup of oils and dirt

Wipe off scum with clean rag- if severe, drain the spa, use a Surface Cleaner to remove any buildup and to protect the spa shell, then refill the spa.

Probable Cause

Solution

High pH

Shock spa with Concentrated Chlorinating Granules or a Spa Shock and adjust pH and/or alkalinity with a pH/Alkalinity Increaser or pH/Alkalinity Decreaser to recommended range.

Low sanitizer level

Shock spa with Concentrated Chlorinating Granules and maintain sanitizer level.

Probable Cause

Solution

Low pH

Adjust pH and/or alkalinity with a pH/Alkalinity Increaser or pH/Alkalinity Decreaser to recommended range.

Low sanitizer level

Shock spa with Concentrated Chlorinating Granules or a Spa Shock, and maintain sanitizer level

Probable Cause

Solution

Unsanitary Water

Shock spa with Concentrated Chlorinating Granules or a Spa Shock, and maintain sanitizer level.

Free available chlorine level above 5ppm

Allow free available chlorine level to drop below 5ppm before spa use, ideal amount is 3-5ppm.

Probable Cause

Solution

Total Alkalinity and/or pH is too low

Adjust Total Alkalinity and pH with a pH/Alkalinity Increaser.

High iron or copper in source water

Use a Stain & Scale to inhibit metals

Probable Cause

Solution

Total Alkalinity and/or pH too high

Adjust total alkalinity and pH with a pH/Alkalinity Decreaser. If scale requires removal, drain the spa, scrub off the scale, clean the spa shell with a Surface Cleaner, refill the spa and add Stain & Scale along with the regular water care products.

High calcium content

Add Stain & Scale and balance the water using a pH/Alkalinity Increaser or a pH/Alkalinity Decreaser.
