Interesting, was told you still have to use chemical especially bromine or chlorine as well that they only last 5 years. So you add nothing?approx 10 years ago we changed to an ozonator system for approx $350 installed. Zero chemicals, zero testing zero issues and water is always clear and no foam. Sometimes we don't lift the cover for a month and still nice and clear. Hot tub companies will tell you negative spins but our local guy basically told us otherwise as he is also a water tester and monitor for various treatment plants.
