Common Hot Tub Water Problems And How To Fix Them
The water in a clean and balanced Hot Tub should be clear and inviting. Problems with the water quality aren’t unusual, but luckily, they’re usually easy to fix.
We want you can spend more time enjoying your Hot Tub and less time looking for answers on what’s wrong with your Hot Tubs water, so we’ve put together this handy guide.
Why Is My Hot Tub Water Cloudy?
Insufficient filtration
Check filters, power supply, and filtration Settings
Organic matter
Shock dose with a non-chlorine shock or replace some of the water
Insufficient sanitiser
Test and correct sanitiser level (Chlorine or Bromine) as required
High pH or alkalinity
Test and correct pH and alkalinity (TA) as required using PH Reducer
Too many dissolved solids
Add a water clarifier to froup the particles to aid filtration.
Drain and refill some or all of the water
Why Does My Hot Tub Water Smell?
Organic matter
Shock Dose using non-chlorine shock or replace some of the water
Low sanitiser
Test and correct sanitiser (chlorine or bromine) as required
Low pH
Test and correct pH as required using a pH Increaser
Too many dissolved solids
Drain and refill some or all of the water
Bacteria or algae in water
Shock Dose using non-chlorine shock or replace some of the water. Re-test, if problem still apparent, add system flush and drain and refill. Multi-functional chlorine tablets are recommended to reduce the risk of algae.
Why is There Scum On Waterline?
Not washing before use
Always shower and rinse before use
Fake tan
Do not use hot tubs if wearing fake tan
Foam
Re-rinse bathing costumes after machine washing or have a separate bathingcostume for the spa and only rinse with warm water.
Skin or Eye Irritation From Water
Organic matter build-up
Shock dose using non-chlorine shock,drain and refill some/all of the water. Test for correct pH.
Sanitiser is “combined”
Shock dose using non-chlorine shock, drain and refill some/all of the water. Test for correct pH.
Hot Tub Water With Erratic pH
Low alkalinity levels
Increase Alkalinity (TA) levels (consider adding buffer) This will avoid ‘pH bounce’
Why Does pH resist change?
High alkalinity levels
Decrease alkalinity (TA) with “slug dose” of pH Reducer
(Add three capfuls of pH Reducer (6 heaped teaspoons) to a large plastic test tube already full of water. Shake/stir until dissolved. Turn off all pumps etc. place in middle of spa at elbow depth and empty avoiding disturbance to water. This is called a slug dose)
