I keep toying with the idea of an SWG because it SO cool to re-gen chlorine, but I just can't get past the cost/benefit analysis. The simplest ones run about $1000--and that's at a minimum 10 seasons' worth of bleach. Plus they DO require weekly maintenance and monitoring. I usually add between a 1/2 gallon and a gallon every other day. If we go away, and the pool isn't being used (I cover it) I simply have whoever is watching the house add the 1/2 gallon every other day and ALWAYS come back to a perfect pool.

Since I try to follow my own motto (see below) I just cannot see enough benefit to justify it.
