I changed over to Aquaspa a few months ago and have not regretted it. The products are super easy to use. Cleaning the spa is a doddle. Knowing that the products don't have any 'bad' stuff in them is an absolute bonus for our guests at Hewitts Homestead, safe on their skin, no nasties etc. Highly recommended.

After years of fighting with chlorine and salt systems, AquaSpa has been a real relief. Natural, easy to dose, kind on skin, and cheaper to run than salt was. We even had to replace our heat recirculating pump after the salt unit kept clogging our filters. None of that drama with this product. Wish I'd switched sooner.

A simple, easy-to-use spa treatment system. As a chlorine-alternative product, it leaves your skin feeling clean and comfortable, without the harsh after-effects associated with chlorine.

Fast delivery and an excellent product. Because of skin sensitivity I am unable to use chlorine based sanitiser so am grateful for a quality alternative at aqua spa

Finally, an easy system that keeps our spa cleaner than ever without affecting my sensitive skin. I'm using our spa much more now that I'm not marinating in chlorine. Wish we had heard about this earlier.
