Hello, and welcome to the forum!

I don't know about the people moving away from SWG statement--they are becoming more and more popular in this area (northwestern Louisiana). In fact, I really want to put one on my pool when I find a spare $1200 lying around!!

I will tell you that an inline chlorinator and ozonator will NOT eliminate the need to shock the pool. The inline chlorinator uses trichlor pucks, which sometimes cause pH problems but almost always cause high stabilizer problems, until people learn their water chemistry. As your stabilizer levels rise, so must your baseline chlorine levels, so an inline chlorinator won't be useful as a standalone system for more than about a year before you start having problems. The ozonator will sanitize the water while it's actually inside the unit, but once it's returned to the pool, it then becomes vulnerable to bacterial/viral growth again, which is why you have to maintain a chlorine level in addition to the ozonator. Again, not a standalone sanitizing system. SWG is.

Just my $.02, for what it's worth!
