When we had our pool installed it came with a chlorine cartridge system that we used for the first season. The second season we had the heat pump installed and I had them take out the chlorine system when running the new pipes for the heat pump and I switched to the
BBB method (bleach, borax, baking soda.) I got a
TF-100 test kit (with refills as needed) and spend 5 minutes each day checking the levels and using an app to make any adjustments.
Family and guests always can't believe how clear and "not chemically" the pool is, and I've had people that have salt water pools assume that's what they are swimming in. But, as pointed out a few times, getting the best results (for any method) will only come if you're putting in the necessary time for everything from the needed tasks to educating yourself thoroughly on the ins and outs of what you're doing.
