Synergy is a unique technology for use in any type of pool using automatic or floating feeders. Synergy makes pool care simple by reducing the number of products needed to maintain your pool and requiring less time for regular maintenance. Each Synergy box is a self-contained system that gives you everything you need; add only two products (Synergy Tabs and Synergy Clear) once a week to keep your pool amazingly clear, comfortable and free from algae growth.
