Are you ready to revolutionise your hot tub experience? Say goodbye to chlorine and bromine and hello to eco3spa!
Our Starter Kit will keep your hot tub clean and sanitised for one month. It is the beginning of your journey to a healthier hot tub experience, softer skin and crystal-clear water.
This kit contains: a full bottle of Step 1 Hot Tub Cleaner & Biofilm Remover; a bottle of Step 2 Water Conditioner sufficient for 1 month and a tub of Step 3 Sanitiser tablets (appox 18 tablets sufficient for 17 sessions)
Step 1 will thoroughly clean and flush out biofilm and chlorine or bromine residue from the pipework, preparing your hot tub for a month of eco-friendly bliss. After you've used Step 1 just add the Step 2 Water Conditioner and a couple of Step 3 Sanitising Tablets, jump in and relax.

And after a month of using eco3spa you’ll love the difference: your skin will be soft and hydrated and your water will be free of that harsh chlorine smell. You’ll be more relaxed because you won't have been faffing around testing and balancing your water and you'll wonder why you didn’t switch sooner!
