Amerse Spa Care
We have recently moved our Softub owners to this brand due to market price and availability issues - Same ingredients and 'small grain' chlorine safe for vinyl tubs!
Amerse spa chemicals are an affordable choice and perfect for both soft-sided (vinyl liner) hot tubs such as Softub ( will not void warranty! ), Spa-in-a-box, Splash Tub, Coleman, Intex, etc. and hard sided 'regular' fiberglass/acrylic/ABS spas from all spa manufacturers.
Make sure to check out our Chlorine and Bromine starter kits - which are designed with the exact chemicals you need to get your tub water crystal clear quickly!
