Temporarily out of stock — closest alternative available The SpaGuard Soft Soak Trio Kit is currently out of stock with no restock date from the manufacturer. There's no exact replacement kit, but these two SpaGuard products together cover the same routine — soft, clean, clear water week to week, plus a plumbing flush before you drain and refill: SpaGuard Spa Complete — softens, clarifies & cleans weekly → SpaGuard System Flush — pre-drain plumbing cleaner → Like the Trio, both work with any sanitizer and are not sanitizers or balancers themselves. Spa Complete is dosed weekly; use System Flush before draining and refilling. Follow each product's label directions. Soft Soak Trio Spa Kit is a simple spa water system that requires no measuring for spa with 350-450 gallons of water. Step one is added at start up and uses minerals and salts to enhance the feel of the water. Step 2 is added weekly, it removes water impurities, prevents scaling and corrosion and replenishes the softness of your water. The last step is before draining the tub as it breaks down oils, grime, lotions etc on the spa surface and plumbing.
