Water changed?Start with the safe check
Cloudy, foamy or green hot tub water? Start here.
Cloudy water, foam around the jets and a green tint can look like the same emergency. They are not. Stop using the tub, test what has changed and choose the next step for the problem you can actually see.
Start with the safe first stepThe short answer: test before treating. Check the filter and water age, then choose a focused product, a system clean or a fresh fill.
Before you treatThree useful actions
Before you treat the water, do these three checks.
-
Stop use.Do not soak while the water is visibly abnormal.
-
Test the water.Follow the hot-tub test instructions and the current chemical label.
-
Check what changed.Look at the filter, water age, waterline and anything recently introduced.
Start with what you can seeTest before treating
The first check depends on what you can see.
Green, cloudy and foamy water can come from different problems. Choose the description that matches what you can see, then follow the relevant route.
Stop use and test the water.
Green water can have more than one cause. Test it, inspect the filter and check the age of the fill before choosing a product.
See the green-water routeThree symptomsThree useful next steps
Match the next step to the water problem.
The symptom tells you where to start. Use a product only after the test, filter check or water-change plan supports it.
Stop use before you add anything else.
Green water can be linked to low sanitation, algae, minerals or residue entering the spa. Colour alone cannot tell you which one is responsible, so use it as a reason to investigate.
- Test against the manufacturer's recommended range.
- Inspect the shell, waterline and filter.
- Check the age of the fill and whether the problem keeps returning.
If it keeps returning: Old, heavily contaminated or repeatedly difficult water may need a drain, system clean and refill rather than another quick treatment.
Test first. Shock only when the result supports it.
Cloudiness can come from a loaded filter, old water, an out-of-range result or extra residue. Work through those checks in order so a quick treatment does not hide the real problem.
- Compare the test result with the recommended range.
- Clean or replace the filter only as its instructions allow.
- Consider whether the fill is old or difficult to balance.
If the test supports a shock: AquaSPArkle Spa Fusion Oxidiser is a 35g chlorine-shock sachet; one sachet treats up to 1500L. Match the label to your water volume, then retest. It does not replace a filter clean or water change. Shop AquaSPArkle Spa Fusion
Remove the likely sources before using No Foam.
Cosmetics, moisturiser, hair products, detergent residue and drinks can add to foam. Rinse, check the filter and test the water before treating the surface.
- Rinse off personal-care products before getting in.
- Rinse swimwear thoroughly after washing.
- Check the filter, water age and test result.
If foam is the problem: Outdoor Living No Foam is a 1L anti-foam liquid for visible foam. It does not affect pH and can be used alongside most sanitisers. Use it for foam, not green or cloudy water, and still check the filter and test result. Shop Outdoor Living No Foam

When the problem keeps returningClean the system
When the same problem returns, reset the water properly.
Residue can remain in the filter or pipework and return to the fresh fill. Hot Tub Flush Filter & Pipe Cleaner is for that cleaning step during a water change; it does not make unsuitable water safe by itself.

Before you use the tubUseful answers
Water-care questions, answered plainly.
Do not use it while the water is visibly abnormal or until your tests and the manufacturer's guidance show that it is suitable. If you cannot bring the water into the recommended range, stop and ask Outdoor Living or a qualified professional for help.
Stop using the hot tub and test the water. Then check the filter, the age of the water and anything recently introduced such as cosmetics, detergent residue or drinks. Avoid adding several products before you know which problem you are solving.
No. Outdoor Living No Foam is for visible foam after you have reduced likely sources such as personal-care or detergent residue. It does not replace testing, filter cleaning or a fresh fill when those are needed.
A fresh fill is worth considering when the water is old, heavily contaminated, difficult to balance, or keeps returning to the same cloudy or foamy state after the filter and pipework have been cleaned. Follow the hot-tub manufacturer's guidance and clean the system as part of the reset.
No. AquaSPArkle Spa Fusion Oxidiser is one chlorine-shock step, not a test or a guarantee that water is ready to use. Match the 35g sachet to the current label and your water volume, then test again.
