Problem Possible Cause Solution
Cloudy Water
• Dirty Filter
• High TDS Levels
• High pH or alkalinity
• High calcium count
• Dissolved solids
• Dissolved solids
• Clean lter with lter cleaner
• Drain and rell with fresh
water
• Check and adjust using pH/
Alkalinity Down
• Drain halfway and rell
• Add clarier to your water
• Shock with sanitizer you
currently use
Brown Water
• High mineral count
• Low alkalinity level
• Low sanitizer level
• Add “Stain & Scale”
• Test and add pH/Alkalinity Up
• Test and add sanitizers
Green Water
• Algae growth • Shock with sanitizer
Yellow Water
• Low pH • Add pH Up
White Scale Deposits
• Low sanitizer level • Test and add sanitizer
Excessive Foaming
• Soft water
• High TDS level
• High contaminant level
• Test and add “Liquid Calcium”
• Drain and rell the hot tub
• Add one capful of “Foam
Away”
Waterline Scum Ring
• Inadequate ltration
• High content of oils
• Check and clean lter(s)
• Add “Natural and Clear”
Pitting of Metal Fixtures
• Low alkalinity or pH • Check and add pH/Alkalinity
Up
Erratic pH Test Results
• Low alkalinity
• Sanitizer level too high
• Old pH indicator strip
• Add pH/Alkalinity Up
• Remove cover and turn on
bubbling system
• Check expiration date and
replace
Musty Odor
• Bacteria/algae growth • Shock the water with
sanitizers
Eye Irritation
• Low pH level
• Low sanitizer level
• Test and add pH/Alkalinity Up
• Test and add sanitizer
