If you want to cut some expense from pool maintenance, consider going salt system for the pool. Have a professional ensure your pool could be switched beforehand (corrosion resistance)
Several users on »www.troublefreepool.com
have measured how much electricity the chlorine generator in their salt pool consumes and found that they aren't saving any money vs. buying chlorine. Then there's the $1,000+ upfront cost and the $500 cell replacements that you have to do every 4-5 years. It IS more convenient, but is doesn't save you any money.
