Thanks for the replies...I've been doing a ton of reading and there's so much information it almost overload! I've had pools all my life since I was about 6 years old and I THOUGHT I knew how to treat the water to keep it clear. I think I'm leaning towards a SWCG system, but maybe not this year. I'm going to keep investigating them during the year and make a decision during the winter months and install it in the early spring for startup. Unless that's not a good time to do so. Any feedback on when making the change to a SWCG is best?
