Spa Treatments
Browse our range of spa pool and hot tub chemicals. Spa water chemistry differs from swimming pools due to smaller water volumes, higher temperatures, and more frequent use, making correct dosing and regular testing essential for safe, comfortable water.
What's in this collection
- Sanitisers. Chlorine and bromine-based sanitisers to keep spa water free of bacteria and contaminants.
- pH balancers. pH increasers and decreasers to maintain the correct pH range of 7.2 to 7.6.
- Alkalinity adjusters. Total alkalinity products to stabilise water chemistry and protect equipment.
- Calcium adjusters. Calcium hardness products to prevent corrosion and scale build-up.
- Clarifiers. Spa clarifiers to clear cloudy water and improve filter efficiency.
- Pipe cleaners. Spa flush and pipe cleaning products to remove biofilm and residue from plumbing.
- Specialty treatments. Simple Silver and other low-chlorine alternative treatments for sensitive users.
