What better way to keep fountains, bubblers and disappearing waterfall features clean and clear all year long then to use both Sublime and Sparkle together. Sparkle works to prevent stains, sludge, mineral deposits and dead organic contaminants from forming in basins. SubLime deep cleans to remove limescale and calcium deposits to ensure a new appearance. This combination includes one 8 ounce bottle of Sparkle and one 8 ounce bottle of SubLime. Apply 1 oz of Sparkle and Sublime for every 10 gallons of water once a week.
