I appreciate all the great responses. I think we are going with a SWG, as we are dealing with kiddos with eczema and they get rave reviews from everyone I can find that owns one. As an aside I had additional conversations with the PB as to what he recommended. He suggests pucks and explained to me that you just partially drain your pool once a year. He never heard of the TFP way. He also runs a pool cleaning company and is shoving pucks in all his customers pools. He claims it is impossible to avoid partial draining. Unfortunately he didn't have a good answer to drought years where it is illegal to drain and fill a pool.
So like many Pool BUILDERS he's good at that...but sort of sucks at pool chemistry. Thankfully you know what you're dealing with and can judge for yourself what to do.
