Muttley, I would go one step further than Ben. An SWCG system will NEVER pay for itself versus using bleach and liquid chlorine and our methods. Not unless the price of SWCGs and replacement cells come WAY down in price.

I have an SWCG and I love. I've had pools since 2000 and this year was the first with my SWCG. But a replacement cell is between $500-$700 and you have to buy one every 5 years. For $100/year I can EASILY chlorinate my pool. But, the rest of my SWCG cost about $700 (with the cell it was about $1200) and I'll NEVER recoup that starting cost.

But that's not why I bought it. It was for the OTHER reasons Ben mentioned.
